Greetings,<br />

I hope everyone had a wonderful<br />

Thanksgiving celebrating with<br />

family and friends. I can’t<br />

believe we are at the start<br />

of the winter season already<br />

with sightings of snow and<br />

frigid temperatures. I’m sure<br />

you have successfully prepared<br />

your heating systems checking<br />

safeties, looking for cracked<br />

heat exchangers, examining<br />

water pressure gauges, changing<br />

steam traps and removing<br />

and cleaning burners, but it’s<br />

important to remember to<br />

monitor continuously throughout<br />

the winter season. Remember<br />

to reach out to our Associate members who can expertly assist you in<br />

completing these tasks.<br />

The Chief Engineers Association annual holiday event will be held on<br />

Wednesday, Dec. <strong>12</strong>th, at the Sheraton Hotel. As we come together with<br />

the board of directors, members and guests to celebrate the season, it’s<br />

also important to remember those in need. Every year, the association<br />

features a charity during the <strong>December</strong> meeting. We ask for donations<br />

and contribute all door monies to the cause. This year, the organization<br />

we will be supporting is A New Direction Beverly Morgan Park (AND),<br />

a grassroots group seeking to help women, men and children who<br />

are victims of domestic violence. A New Direction provides crisis<br />

intervention, safety planning, counseling, education and support as well<br />

as legal advocacy and resources to navigate the legal system to those<br />

in need. So how can you, as members, help? Please bring monetary<br />

donations or gift cards (grocery, gas, clothing stores, Visa, etc.) as your<br />

entry into the event. I thank you in advance for your generous support<br />

and partnership in benefiting this organization.<br />

I would also like to take this time to thank all of our members for<br />

their support in <strong>2018</strong>, vendors for their advertising and sponsorship,<br />

engineers for attending events and engagement with our sponsors<br />

and for bringing guests to show off our organization. As a board, we<br />

work hard to provide a variety of events so our vendors can showcase<br />

their products and services and engineers can come network. The<br />

relationships built at these events foster collaboration and provide<br />

endless resources. Thank you for being a part of this growing<br />

organization.<br />

I wish you and your families the very best as we enter the holiday<br />

season. I look forward to seeing everyone at the <strong>December</strong> meeting so<br />

we can toast to a successful <strong>2018</strong>.<br />

Sincerely,<br />

Dan Carey

In Brief<br />

Mold Cleanup Kept Suburban Chicago<br />

School Closed<br />

CALUMET CITY, Ill. (AP) — Officials kept a suburban<br />

Chicago school closed while crews worked to cleanup<br />

mold found inside the building.<br />

Wentworth Junior High School in the southern suburb<br />

of Calumet City was kept closed to facilitate remediation<br />

efforts. The school district also shut down its<br />

elementary and intermediate schools on the scheduled<br />

first day of classes, but opened those buildings the<br />

following day.<br />

District superintendent Troy Paraday said that officials<br />

were taking the matter very seriously and are committed<br />

to giving students a safe learning environment.<br />

U of I Professor to Head Planned<br />

Chicago Innovation Center<br />

CHICAGO (AP) — The University of Illinois has picked<br />

one of its own professors to head an effort to build<br />

and operate a major innovation center in Chicago’s<br />

South Loop.<br />

William H. Sanders has led the engineering department<br />

at the university’s Urbana-Champaign campus<br />

since 2014 and will oversee what’s called the Discovery<br />

Partner’s Institute. The Chicago Tribune reports those<br />

duties will include leading construction of the center,<br />

supervise all faculty and staff hiring and oversee all<br />

new corporate and academic partnerships.<br />

Once it is operating, the center is expected to employ<br />

more than 100 faculty members who will specialize in<br />

research on computing and big data, environment and<br />

water, food and agriculture and health and wellness.<br />

School officials say the center will accommodate more<br />

than 2,000 students a year.<br />

Workers Fixing Bridge Find Note Left<br />

by Crew Who Built Span<br />

ALBANY, Ind. (AP) — Construction workers repairing<br />

a central Indiana bridge discovered a note apparently<br />

left behind by the crew who built it 80 years ago.<br />

The jar shattered but it contained a tattered slip of<br />

paper that reads “List of last crew working on this<br />

bridge,” and includes the names of 17 carpenters,<br />

cement finishers and others it says worked on the span<br />

during 1938 and 1939.<br />

Henry calls it “a neat piece of history” that the town<br />

near Muncie plans to display.<br />

Indiana City Won’t Restart Coal Plant<br />

Despite Relaxed Rules<br />

LOGANSPORT, Ind. (AP) — A northern Indiana city’s<br />

coal-burning power plant won’t be reopening despite<br />

the Trump administration’s plan to relax restrictions on<br />

greenhouse gas emissions from such facilities.<br />

Logansport Municipal Utilities shut down its plant in<br />

early 2016 after deciding it couldn’t afford updates<br />

needed to meet rules established under former President<br />

Barack Obama.<br />

City utilities Superintendent Paul Hartman tells the<br />

Pharos-Tribune that a coal-fired power plant generally<br />

can’t be restarted after several months out of action.<br />

The plant generated about 30 percent of the Logansport<br />

utility’s electricity. Duke Energy has provided<br />

it all since the plant’s closure. Some equipment inside<br />

the former plant has been sold for scrap.<br />

Energy Department Says Wind Power<br />

Projects Continue in US<br />

OKLAHOMA CITY (AP) — The U.S. Department of<br />

Energy reports that the continued construction of<br />

wind-power generating stations is bringing down both<br />

the cost of building the installations and the price for<br />

wind-generated electricity.<br />

The report in August shows Texas leads the nation<br />

with 22 gigawatts of wind capacity, followed by Oklahoma,<br />

Iowa, California and Kansas with each at more<br />

than 5,000 megawatts.<br />

A gigawatt is 1 billion watts of power; a megawatt is 1<br />

million watts.<br />

cents per kilowatt hour in 2009 to about 2 cents per<br />

kilowatt hour in 2017.<br />

The U.S. Energy Information Administration says the<br />

average home in the U.S. uses 897 kilowatt hours per<br />

month.<br />

Man Accused of Selling Historic Bridge<br />

Metal Seeks Dismissal<br />

HAMMOND, Ind. (AP) — A northwestern Indiana<br />

scrap-metal dealer accused of demolishing a historic<br />

bridge and selling the metal is seeking to have the<br />

federal charge he faces dismissed.<br />

Kenneth Morrison argues in a motion filed Aug. 27 in<br />

federal court in Hammond that questions about who<br />

owned the bridge warrant his indictment being tossed.<br />

Morrison operates T&K Metals in Whiting. He was<br />

charged in 2017 with interstate transportation of<br />

stolen property for allegedly taking metal from a<br />

long-unused 1910 railroad drawbridge and selling it to<br />

an Illinois scrapyard for $18,000.<br />

The Post-Tribune reports Morrison’s attorney says<br />

investigators told a grand jury the city of Hammond<br />

“conclusively” owned the bridge, but that public<br />

records and correspondence between the city and a<br />

railroad company showed they couldn’t say for certain<br />

who had the bridge’s deed.<br />

Illinois Football Program Gets Millions<br />

to Build New Center<br />

CHAMPAIGN, Ill. (AP) — The University of Illinois Foundation<br />

is getting a $20 million donation, including $15<br />

million for the Fighting Illini Football Performance<br />

Center.<br />

The money is coming from the H.D. Smith Foundation.<br />

Henry Dale Smith started H.D. Smith, a medical wholesale<br />

company based in Springfield, Ill.<br />

Chris and Dale Smith say they’re honoring their late<br />

father and mother Betty and the couple’s passion for<br />

Illinois football.<br />

The Smith Foundation’s gift also includes $3 million for<br />

athletes to return and complete their degrees.<br />

Hammond Schools to Provide Bottled<br />

Water at 7 Buildings<br />

HAMMOND, Ind. (AP) — Hammond’s school superintendent<br />

says bottled water will be provided to students<br />

in buildings where elevated lead levels were<br />

found in drinking water.<br />

Superintendent Walter Watkins said in an email to<br />

staff on Aug. 30 that seven buildings, including six<br />

schools, registered lead levels above the recommended<br />

Environmental Protection Agency threshold when<br />

tested on Aug. 9-13.<br />

The Post Tribune reports the high lead levels were<br />

found in 19 fountains at the six schools. Watkins says<br />

those fountains were taken out of service until further<br />

testing is done. Bottled water will be provided at each<br />

building.<br />

Opening of Pedestrian Bridge Delayed<br />

for Additional Testing<br />

FORT WAYNE, Ind. (AP) — The opening of a pedestrian<br />

bridge that will link two college campuses in Fort<br />

Wayne has been pushed back by additional testing of<br />

the span.<br />

The Parker Cole Crossing was initially set to open in<br />

June, spanning a busy roadway to link Purdue University<br />

Fort Wayne and Ivy Tech Community College.<br />

But the Indiana Department of Transportation added<br />

additional testing to ensure the $4.5 million bridge<br />

meets design and construction standards.<br />

Greg Justice is Purdue Fort Wayne’s executive director<br />

of facilities management. He tells The Journal Gazette<br />

that the added testing is primarily responsible for the<br />

delayed opening of the bridge, which about 1,000<br />

students are expected to use daily.<br />

Albany Town Marshal Shannon Henry says workers<br />

were using a jackhammer to break up concrete on<br />

Bridge 701 last week when a glass jar fell out.<br />

The report says wind energy provided 6.3 percent of<br />

the nation’s electricity supply in 2017.<br />

The average price for wind power has fallen from 7<br />

The Henry Dale and Betty Smith Football Center<br />

will be a 107,000-square-foot facility with space for<br />

strength and conditioning, sports medicine, locker<br />

rooms, offices for coaches and more. Construction will<br />

be completed before the 2019 season.<br />

Bob Sanford of Sanford and Hawley was elected Chair of NLBMDA’s <strong>2018</strong>-<br />

2019 leadership team.<br />

CHICAGO, Ill. — The National Lumber and Building Material<br />

Dealers Association (NLBMDA) elected its new leadership<br />

team last month at the ProDealer Industry Summit in<br />

Chicago, Ill. At its annual meeting, the NLBMDA Board of<br />

Directors elected Robert P. Sanford as the new Chair of the<br />

association. Mr. Sanford is president of Connecticut-based<br />

Sanford and Hawley and is replacing outgoing chair Rick<br />

Lierz, President and CEO of Franklin Building Supply in Boise,<br />

Idaho.<br />

“I am honored and humbled to be the next chair of the<br />

National Lumber and Building Material Dealers Association,”<br />

said Mr. Sanford. “Housing, and by extension, the<br />

lumberyards and building material dealers that supply the<br />

industry, are integral to a vital economy and to our nation’s<br />

continued success. With the ever-changing legislative<br />

landscape in Washington, it is more important than ever<br />

that we continue to represent our collective interests in our<br />

nation’s capital so that we may all thrive in the years ahead.<br />

With an ear to the legislative machinations in Washington,<br />

and an eye to the technical advancements that keep our<br />

Founded in 1884, Sanford and Hawley is the oldest business<br />

in Farmington, CT, owned by the same family and at the<br />

same location. The Hawleys left the company years ago, but<br />

the Sanford Family has survived the many obstacles that have<br />

been thrown their way. The company is now operated by<br />

Frank, Bob and Ted Sanford, along with Bob’s son, Bobby.<br />

“Bob has been an active NLBMDA and NRLA member for<br />

decades and has a tremendous amount of knowledge and<br />

expertise in the LBM industry. He has consistently shown a<br />

passion for serving others. I am truly honored to have the<br />

opportunity to continue to work with Bob as we are both<br />

committed to moving the association forward as he becomes<br />

NLBMDA Chair,” said NLBMDA President & CEO Jonathan<br />

Paine. “I also want to thank Rick Lierz for his tremendous<br />

leadership this past year. Together Rick and Bob have gone<br />

above and beyond and it has been an invaluable experience<br />

working with them.”<br />

AKF’s Mark Richter to Chair World’s<br />

Foremost Tall Buildings Design Award<br />

Panel<br />

Hidden Emergency Lighting Preserves<br />

Building Aesthetics While Meeting Code<br />

Richter’s 26-year career includes the design of iconic New<br />

York City buildings such as One57, Central Park Tower, and<br />

520 West 28th, the new luxury condominium along the Highline<br />

designed in collaboration with Pritzker Prize-winning<br />

architect Zaha Hadid. 520 West 28th won AKF an American<br />

Council of Engineering Companies New York State Diamond<br />

Award for engineering excellence. Mark also added that the<br />

CTBUH gathering is the perfect venue to celebrate professionals<br />

whose passion is engineering healthy, sustainable tall<br />

buildings.<br />

“As buildings across the globe continue to get taller and taller,<br />

a comprehensive approach to sustainability is critical. AKF<br />

has always delivered design enhancements that are above<br />

energy code, mindful of the surrounding environment, and<br />

conscious of their energy impact. I look forward to joining<br />

other jurists who share these values.”<br />

AKF’s Mark Richter will serve as 2019 Jury Chair for the CTBUH Annual<br />

Awards’ MEP Engineering Panel.<br />

NEW YORK (GLOBE NEWSWIRE) — AKF, a global leader in<br />

engineering, technology, design, consulting and commissioning,<br />

is excited to announce that Partner Mark Richter, PE has<br />

been appointed by the Council on Tall Buildings and Urban<br />

Habitat (CTBUH) to serve as 2019 Jury Chair on the MEP Engineering<br />

panel for the CTBUH Annual Awards.<br />

“For nearly 50 years, CTBUH has been a leading authority on<br />

tall building and urban design trends,” said Richter. “And<br />

today, as technology continues to change the landscape for<br />

MEP professionals around the globe, CTBUH continues to set<br />

the standard for the construction and design of next-generation<br />

buildings. I am honored to chair the MEP Jury.”<br />

Richter, who has earned praise for his expertise in the<br />

planning and design of high-rise and mixed-use properties,<br />

noted that to date AKF has been instrumental in the design<br />

and commissioning of more than 30 high-rise and super-tall<br />

structures around the globe. This includes work on four of<br />

Mexico’s five tallest buildings, as well as Three Sixty West in<br />

Mumbai, which will be India’s tallest building upon construction<br />

completion.<br />

Many of Isolite’s architectural emergency lighting solutions are virtually invisible during normal lighting conditions, eliminating unattractive surface mounted<br />

emergency lights.<br />

While emergency lighting is critical to life safety and must<br />

function to code, no one wants to see the devices ruin the<br />

aesthetics of a building’s interiors. So industry professionals<br />

are increasingly keeping the lights hidden or camouflaged<br />

until needed to ensure it artfully blends in with its surroundings.<br />

“From the standpoint of interior architectural aesthetics, traditional<br />

wall or ceiling-mounted emergency lighting systems<br />

can be sort of an eyesore that establishments with a more<br />

refined look want to eliminate because it can take away<br />

from the architectural experience,” says John Decker, IALD of<br />

Lighting Design Studio, a multi-disciplinary firm. The company<br />

has completed lighting projects for a variety of commercial<br />

spaces including resort hotels, spas, casinos, restaurants,<br />

retail, and office spaces.<br />

Now an innovative option, fixtures completely hidden<br />

behind closed-door panels on walls or ceilings, is helping to<br />

meet emergency lighting code. Only in the case of emergency<br />

or power outage do the doors open and the emergency<br />

lights emerge to ensure sufficient light along the path of<br />

egress, as mandated by the NFPA and International Building<br />

Code (IBC). For even greater discretion, the panels can be<br />

painted, wallpapered over, and placed in locations out of the<br />

line of sight to make them completely inconspicuous.<br />

Enhancing Aesthetics and Ensuring Safety<br />

Design professionals often meticulously plan the aesthetics<br />

of various building elements including style, form, and ma-<br />

terials in a wide range of structures. This can involve upscale<br />

hotels, resorts, restaurants, retail centers, office buildings,<br />

and concert halls as well as historic courthouses, museums,<br />

city halls, state and federal buildings.<br />

A challenge, however, occurs when urgent project timelines<br />

lead to unfortunate compromises in building aesthetics, often<br />

in the area of emergency lighting, at the last minute.<br />

“When building owners and end users pay for architectural<br />

services, they may have a wonderful structure with everything<br />

considered in the space – until the end of the project<br />

when ill-considered, utilitarian, even ugly, emergency lighting<br />

is installed to provide light for emergency egress,” says<br />

Decker.<br />

“In nicer hospitality, entertainment, office, and service settings<br />

with refined interiors –like hotels, resorts, restaurants,<br />

spas, casinos, museums, historic districts, and themed amusement<br />

parks – foreign looking emergency lighting fixtures<br />

mounted to the walls or ceiling can look really out of place,”<br />

he adds.<br />

While there are many emergency lighting approaches available<br />

that will sufficiently provide one foot candle of illumination<br />

along the path of egress as specified by the NFPA,<br />

these options typically begin with deciding on the type of<br />

power source that will be used in the event of a power outage.<br />

Often, existing architectural lights are incorporated if possible,<br />

powered by centralized inverters or generators. However,<br />

when that is not sufficient, dedicated battery powered<br />

emergency lights may be required, but these can be obtrusive<br />

and unattractive.<br />

“If the engineer proposes to put ugly, ‘bug-eye’ emergency<br />

lights in a beautiful interior space, we try to find aesthetic<br />

solutions that still meet the code requirement of providing<br />

enough egress lighting for emergency situations – while<br />

maintaining the beauty of that space,” says Decker, who is a<br />

trained architect.<br />

“Bug-eye” is the colorful term used to describe typical<br />

emergency lighting that surface mounts on the wall with a<br />

battery box under two lamps that resemble a bug’s eyes.<br />

Decker says there are superior methods for hiding, or concealing,<br />

emergency lighting.<br />

The first method is to utilize a backup battery hidden in the<br />

housing of a lighting fixture, such as a recessed downlight or<br />

suspended linear luminaire. In the event of a power failure,<br />

the battery will then supply emergency lighting for a designated<br />

amount of time as determined by code.<br />

However, Decker points out another alternative. He points<br />

to Isolite, a manufacturer of specification-grade emergency<br />

lighting products. The company offers the Genie, along with<br />

a more compact version called the Mini Genie, that remain<br />

fully recessed behind two flat panel doors installed in the<br />

ceiling or walls until needed.<br />

“With the Genie and Mini Genie, you have a concealed look<br />

architecturally, but under normal loss of power the battery<br />

kicks in, the doors open, and the lamps pop out to light the<br />

way,” says Decker.<br />

“The recessed solution lends itself to maintaining the integrity<br />

of the architectural interior space, so it works functionally<br />

and aesthetically,” he adds.<br />

While having emergency lights emerge from door panels<br />

when needed keeps them out of the way, lighting professionals<br />

like Decker also value the ability to camouflage them<br />

as well.<br />

With both of the units, the flat panel doors lay flush with the<br />

trim and mounting surface, and exterior trim can be painted<br />

or wall-papered to match any color or decor so as to blend in<br />

with the architecture.<br />

Because these emergency lights are fully self-contained and<br />

can be recessed into walls or ceilings, they are virtually invisible<br />

during normal lighting conditions, and thus eliminate<br />

unsightly, surface mounted emergency lights and battery<br />

packs.<br />

While this approach can enhance the aesthetics of new<br />

builds and retrofits, it is particularly helpful in preserving the<br />

“look and feel” of historic buildings, which still must accommodate<br />

life safety and security needs, as well as update<br />

building systems appropriately.<br />

Such implementation strikes a balance between retaining<br />

original building features and accommodating new technologies<br />

and equipment.<br />

In fact, the Mini, which can wall mount with a total depth of<br />

3.5”, is also well suited for shallow plenum applications, the<br />

narrow space between the structural ceiling and drop-down<br />

ceiling used for HVAC air circulation.<br />

The company also offers recessed LED emergency lighting<br />

mounted 18” above the floor. The product directs light to<br />

the floor to more effectively illuminate the path of egress<br />

than traditional ceiling or wall mounted emergency lights.<br />

“Lighting the path of egress from a lower vantage point<br />

makes sense in situations where there is a fire because all the<br />

smoke rises and [if it were higher] it could block some of the<br />

light,” says Decker.<br />

With such new tools to make emergency lighting less conspicuous,<br />

building design professionals can now preserve<br />

elegant, architectural quality aesthetics while meeting emergency<br />

lighting and life safety codes.<br />

“Wherever aesthetics are valued, concealing emergency<br />

lighting should be an option,” concludes Decker.<br />

“When the Isolite products are fully recessed and the panels<br />

are painted or wallpapered to match their surroundings, you<br />

really cannot see them unless you are specifically looking,”<br />

says Decker.<br />

For more information, contact Isolite at 31 Waterloo Avenue,<br />

Berwyn, PA 193<strong>12</strong>; call 800-888-5483; or visit them on the<br />

web at www.isolite.com<br />

According to Decker, the design and engineering team<br />

utilized this approach for emergency lighting in the themed,<br />

Camp Jurassic caves at Universal’s Islands of Adventure in<br />

Orlando.<br />

“We used a Genie product, and it was painted out so you<br />

really couldn’t see it unless you were looking for it,” he says.<br />

“It maintained the integrity of the aesthetics.”<br />

Building Up With Precast Concrete<br />

Panels<br />

BEAUSEJOUR, Manitoba, Can. — Builder Syed Bokhari passionately<br />

believes in creating durable, energy-efficient housing<br />

for seniors. That dedicated focus has led him to explore<br />

creative construction practices — including the use of precast<br />

concrete panels from Superior Walls by Magnis.<br />

“I first saw a Superior Walls basement foundation two years<br />

ago and thought it was a great way to build,” says Bokhari,<br />

president of Noble Builders in Winnipeg, Manitoba. “Then I<br />

went and viewed a wide variety of different Superior Walls<br />

basements and decided this was the product I wanted to use.<br />

The speed of installation truly accelerates the work on site,<br />

plus the energy-efficiency features are an asset in our area.”<br />

Working with a design created by T-Square Techniques, Inc.,<br />

Noble Builders is now approaching the final stages of construction<br />

on a three-story seniors residence at 51 Kaatz Drive<br />

in Beausejour, Manitoba. The team decided to “build up”<br />

with precast concrete panels and created the entire exterior<br />

of the building — plus the interior elevator shaft — with<br />

custom panels supplied by Superior Walls.<br />

“We selected the precast wall product primarily for its speed<br />

in erecting and enclosing the building structure,” says Brian<br />

L. Mansky, principal owner and chief designer at T-Square<br />

Techniques, Inc. in Winnipeg. “This is technically a far superior<br />

building envelope system as compared to standard wood<br />

frame construction. While this is our first time specifying<br />

Superior Walls for a project, we’ve been so impressed with<br />

the product that we’re considering it for other projects.”<br />

Reliable Concrete Walls<br />

The 35-unit independent living residence for seniors at 51<br />

Kaatz Drive incorporates Superior Walls Xi Plus panels into<br />

the building envelope.<br />

“The exterior walls include 2,400 linear feet of eight-foot tall<br />

Xi Plus panels, and then there’s an additional <strong>12</strong>0 linear feet<br />

of 10-foot tall Xi Plus panels for the elevator shaft,” says Ray<br />

Wentz, special projects manager at Superior Walls by Magnis.<br />

“This is the first multi-story, above-ground application of our<br />

products in this area.<br />

Precast concrete panels offer many advantages, including durability, energy efficiency and ease of installation.<br />

“The advantages of using precast concrete panels in this type<br />

of building construction are amazing. Each wall panel is custom<br />

made to the exact specifications of the plan. The panels<br />

install quickly and resist mold, rot, fire and noise. These are<br />

incredible features for a senior living facility.”<br />

Superior Walls Xi Plus wall panels (Canadian markets) feature<br />

steel reinforced concrete and 5″ Neopor® Rigid Thermal<br />

Insulation to create a barrier against sidewall water penetration.<br />

The panels are custom designed and constructed in<br />

a factory-controlled setting. Unique features of the Xi Plus<br />

wall panels include:<br />

• 5,000+ PSI concrete<br />

• Steel-reinforced top bond beams, concrete studs and footer<br />

beams<br />

• Horizontal steel rebar inside top and bottom beams<br />

• Vertical steel rebar inside each stud<br />

• Galvanized steel stud facing ready for drywall finishing<br />

• Insulated corners, studs and bond beams<br />

• A four-inch insulated footer beam<br />

• 5″ Neopor Rigid Thermal Insulation to provide an insulation<br />

value of R-24<br />

• Four insulated access holes are included in each standard<br />

stud to provide greater ease in wiring and plumbing.<br />

Bokhari agrees that the benefits of the concrete panels for<br />

the project make them a winner for the senior living facility.<br />

“We had the shell up on the structure in less than four<br />

months, which is impossible to achieve with poured concrete,<br />

concrete blocks or traditional wood frame construction,” says<br />

Bokhari.<br />

The “shell” of this structure includes a broom finish to the<br />

concrete exterior, providing a scratch coat for acrylic stucco<br />

and cultured stone accents. The finish can also be painted.<br />

“This is a new way of building,” says Bokhari. “It’s faster<br />

and more reliable than past building methods. I can see us<br />

working on many projects in the future with Superior Walls<br />

foundations and above grade applications.”<br />

Interior Elevator Shaft<br />

One of the most beneficial aspects of using precast concrete<br />

panels on the 51 Kaatz Drive project came in the construction<br />

of the elevator shaft.<br />

While concrete block construction has been the industry<br />

standard for elevator shafts in years past, the fast installation<br />

of Superior Walls speeds up the construction schedule. As<br />

well, these walls remain non-combustible and heat transfer is<br />

minimized as they are insulated panels.<br />

“A concrete stairwell or elevator shaft can give building<br />

occupants additional time to escape from a burning structure<br />

because the material resists the movement of the fire,” says<br />

Wentz. “A zone delineated by concrete within a building can<br />

provide escape routes during a fire by maintaining structural<br />

integrity and allowing people to get away from the building.<br />

At the same time, this allows firefighters to more safely enter<br />

the structure and fight the fire from multiple locations and<br />

levels.”<br />

During the construction of 51 Kaatz Drive, the Superior Walls<br />

precast concrete panels were placed in the elevator shaft<br />

with the concrete side faced inward and with a fireguard<br />

facing outside. The exterior facing wall was covered with<br />

5/8” drywall providing the structure with its appropriate fire<br />

rating.<br />

“The new technology in precast concrete panel construction<br />

is now better suited to Canadian conditions,” says Wentz.<br />

“We are able to apply an integrated Styrofoam and insulating<br />

component to the panels that brings it up to a R24<br />

rating. Combined with the speed of installation on the job<br />

site, this is a real win for the construction industry.”<br />

Wisconsin Man Repairs Museum’s<br />

Flood-Damaged Vehicles<br />

By Barry Adams | Wisconsin State Journal<br />

SPRINGFIELD, Wis. (AP) — Chris Beebe’s automotive resume is<br />

storied.<br />

For more than 45 years he founded, owned and operated<br />

Foreign Car Specialists in Madison, has raced a wide range<br />

of vehicles, worked as a racing instructor, written for automotive<br />

publications and developed hybrid vehicles, including<br />

the prototype for the Chevy Volt. From 2008 to 2011, he and<br />

a team even competed for the Automotive X-Prize.<br />

Water reached the bottom of the windows of the museum’s<br />

historic buildings and filled not only the passenger compartments<br />

of the cars but also the engines, lights and any other<br />

cavity below the waterline. And the water was far from<br />

clean. It contained not only mud, debris and likely sewage,<br />

but also oil from the vehicles. So when the water receded,<br />

every German Messerschmitt and Heinkel Bubblecar, East<br />

German Trabant and English Bond were not only soaked but<br />

left covered in a film of oil.<br />

Beebe’s latest effort is testing all of his skills, patience and his<br />

73-year-old knees and back.<br />

Since late August, Beebe has been self-sequestered in a<br />

storage shed on a farm north of Middleton and just west of<br />

Ashton where he is working to dry out, repair and restart 15<br />

cars and 13 motorcycles from the Midwest Microcar Museum<br />

in Mazomanie that were damaged in late August when<br />

torrential rains flooded the village.<br />

Even the Amphicar, a car that doubles as a boat, was damaged.<br />

It failed to float and the seals on its doors were compromised,<br />

which flooded the interior.<br />

“I’ve seen everything here but I haven’t seen the internals of<br />

many of these so it’s been a real eye-opening experience,”<br />

Beebe told the Wisconsin State Journal as he took a break<br />

from cleaning the starter for a French-made Renault 4CV.<br />

“You just have to be sensitive as to what water got into<br />

what. It’s really ugly, but at least it’s not salt water, which is<br />

much more corrosive.”<br />

The water quickly receded and the vehicles were pulled from<br />

the six inches of sludge that covered the museum floors before<br />

they were hauled in multiple trips by trailer 22 miles to<br />

the farm shed. But the restoration efforts are complicated by<br />

the design of the vehicles.<br />

The motorcycles are fairly straightforward, but the microcars<br />

have limited access to the engine compartments, so Beebe<br />

wears kneepads and a headlamp. In some cases, he has to<br />

crawl through interiors to reach small openings in the back<br />

of a vehicle to where the engine is located.<br />

And the engines themselves, in many cases, are glorified<br />

lawnmower engines. That means there are no drain plugs, so<br />

motors need to be tilted to drain, which really isn’t an option<br />

since they’re installed in a car body. Putting the vehicles on<br />

a lift doesn’t work because of their odd designs, although<br />

Beebe thought about lifting the cars and then attaching<br />

straps and inverting the vehicles. But because of the logistics,<br />

he has instead chosen to drill into the engines small drain<br />

holes that are then threaded and plugged once the water is<br />

removed.<br />

Humidifiers and fans have been constantly running in the<br />

shop and at the museum buildings, while the seats and other<br />

interior coverings have been removed and are now laid out<br />

on the floor of the shed until they can be repaired and put<br />

back into the vehicles by Vic’s Auto Upholstery in DeForest.<br />

Tags with detailed notes have been attached to each car and<br />

motorcycle indicating what has been done so far in the restoration<br />

process.<br />

“He’s a gift from God,” Carlo Krause, a longtime car collector<br />

who opened the museum in 2015, said of Beebe. “You’d<br />

never find another guy around here that even comes close to<br />

what this guy is doing. I nearly kiss the guy every time I see<br />

him.”<br />

Krause, 78, bolstered his car-collecting hobby after health<br />

problems forced him to retire about 20 years ago from his<br />

business designing and selling components for automated<br />

processing machinery. His father, who also was an electrical<br />

engineer, started the business in the basement of his home<br />

in Lake Geneva. Krause, who lives just outside of Middleton,<br />

and his son, Sven, got the idea for the museum after some<br />

of their microcars were showcased at a three-day car show<br />

at Discovery World in Milwaukee about five years ago. The<br />

exhibit drew more than 4,000 people.<br />

The first museum building was purchased by Krause in 2015<br />

and is located in the former blacksmith shop of John Parman,<br />

who built the facility across the street from his 1864 brick<br />

home that still stands across the street. All of the vehicles<br />

on the ground floor of the building were damaged but 10<br />

microcars on the second floor remain in place and were unscathed.<br />

The remainder of the collection is about 25 yards to<br />

the west in the Mazomanie’s town hall, constructed in 1878<br />

but now owned by the village. Krause began leasing space<br />

in the building in 2017, made improvements to the structure<br />

and had cars and motorcycles on the ground floor and about<br />

15 motorcycles on the second floor.<br />

Most of the 30 microcars in Krause’s free museum are from<br />

the 1950s and 1960s. He even has a few bicycles with motors<br />

built into their rear wheels. The museum, where damages<br />

are estimated at more than $300,000, likely won’t reopen<br />

until next spring. Meanwhile, dumpsters and construction<br />

trailers dot the village where dozens of homes and commer-<br />

cial properties sustained flood damage.<br />

“If you don’t have anything running and you ever want<br />

to sell it, they’re worthless,” Ingrid Krause, Carlo Krause’s<br />

wife, said during a walk through the damaged buildings in<br />

Mazomanie. “What’s sad is that everything was basically in<br />

original condition.”<br />

Microcars became popular modes of cheap transportation<br />

after World War II and were built by manufacturers across<br />

Europe, including by companies that had been making military<br />

equipment during the war. Most of the early microcars<br />

traveled no faster than 50 mph with 200cc to 250cc, one-cylinder<br />

engines, while later models sported slightly larger<br />

motors that increased speeds to more than 70 mph.<br />

Beebe had visited the Microcar Museum just a week prior<br />

to the flood and reached out to Carlo Krause shortly after<br />

learning of the museum’s plight. Just days later he was at<br />

Krause’s farm shed, which holds other cars in Krause’s collection.<br />

Only now it resembles a working museum of repair.<br />

Doors and small hoods to the vehicles are propped open and<br />

even two months after the flood, dehumidifiers and fans are<br />

constantly running in an effort to draw out moisture from<br />

the vehicles.<br />

Beebe and his assistant, Doug Heideman, who worked at<br />

Foreign Car Specialists prior to its closing in 2014, have been<br />

using rags and cleaning solutions to remove mud and oil but<br />

have also flushed engine compartments and chain cases with<br />

a mixture of isopropyl alcohol and WD-40. Wiring has been<br />

repaired and generators, carburetors and anything else that<br />

holds water have been removed (if possible) and dried.<br />

“There was water in everything,” Beebe said. “It’s taken a lot<br />

to get mechanical stuff back working again.”<br />

But the effort to make the microcars whole again has involved<br />

some sleuthing by Beebe, since there are few resources<br />

in the U.S. for repairing the tiny vehicles. So when Beebe<br />

had a question about how much oil was held in the chain<br />

case of a Messerschmitt, he went to a mud-stained membership<br />

publication of a Messerschmitt club that was salvaged<br />

from the floodwaters. Beebe was able to find phone numbers<br />

for two of the four people in the U.S. listed in the 1978<br />

booklet. One of them, from Florida, called back.<br />

“He was so nice. It was really great,” Beebe said. “There are<br />

no manuals for this stuff.”<br />

Divisive Minnesota Mine Wins Permits,<br />

But Faces Challenges By Jeff Baenen<br />

MINNEAPOLIS (AP) — Minnesota regulators on Thursday,<br />

Nov. 1, granted key permits to the long-planned PolyMet<br />

copper-mining project that’s opposed by environmentalists<br />

who fear it could someday foul waters, including Lake Superior.<br />

The state Department of Natural Resources issued permits to<br />

PolyMet Mining Inc. for the company’s proposed NorthMet<br />

project in northeastern Minnesota. The project still needs<br />

permits from other agencies, and likely faces court challenges.<br />

“No project in the history of Minnesota has been more<br />

thoroughly evaluated,” DNR Commissioner Tom Landwehr<br />

said in announcing approval of permits for the project, first<br />

proposed in 2004.<br />

Environmentalists have opposed the mine for fear it could<br />

pollute pristine waters and destroy habitat for gray wolves<br />

and Canada lynx. The project would be located near tributaries<br />

feeding the St. Louis River, 175 river miles upstream from<br />

Lake Superior.<br />

Duluth for Clean Water said the proposed mine “would<br />

create permanent, toxic pollution in the headwaters of Lake<br />

Superior, putting our communities and lives in constant<br />

danger.”<br />

“The massive open-pit mine would destroy huge swaths of<br />

the Superior National Forest and significantly increase annual<br />

CO2 emissions in Minnesota at the worst possible time,” the<br />

group said.<br />

PolyMet contends it can operate the proposed mine near<br />

Hoyt Lakes and Babbitt without harming the environment<br />

while creating hundreds of badly needed jobs on Minnesota’s<br />

Iron Range.<br />

“We look forward to building and operating a modern mine<br />

and developing the materials that sustain and enhance our<br />

modern world,” PolyMet President and CEO Jon Cherry said<br />

in a news release. “Responsibly developing these strategic<br />

minerals in compliance with these permits while protecting<br />

Minnesota’s natural resources is our top priority as we move<br />

forward.”<br />

Paula Maccabee, an attorney for environmental group WaterLegacy,<br />

said environmentalists will likely appeal if permits<br />

are granted, or they could request that the DNR reconsider<br />

its decision.<br />

The agency issued a permit to mine, six water appropriation<br />

permits, two dam safety permits, a public waters work<br />

permit and an endangered species takings permit for the<br />

project. The permit to mine includes a financial assurance<br />

plan — designed to provide enough money so the DNR can<br />

reclaim and close the mine and plant site in case PolyMet<br />

does not — and a wetland replacement plan. The project still<br />

requires water and air quality permits from the Minnesota<br />

Pollution Control Agency and a wetlands permit from the<br />

U.S. Army Corps of Engineers.<br />

Landwehr said the DNR is “confident that the project can be<br />

built, operated, and reclaimed in compliance with Minnesota’s<br />

rigorous environmental standards.”<br />

“Yes, there will be an environmental impact,” Landwehr told<br />

reporters. “Our job is to ensure those environmental impacts<br />

are within state standards, and whenever required, they are<br />

mitigated.”<br />

Maccabee and other environmentalists questioned why the<br />

DNR did not conduct a contested case hearing for an independent<br />

review before issuing the permits. But Landwehr<br />

said the project did not meet the standards under state law<br />

for such a trial-like hearing.<br />

“These permits should be reviewed by an independent<br />

administrative law judge to establish the facts before permit<br />

decisions are made,” Kathryn Hoffman, chief executive of<br />

the Minnesota Center for Environmental Advocacy, said in a<br />

statement, noting that such hearings are routine for pipelines<br />

and power plants. “It is special treatment for PolyMet<br />

to skip this vital step for the first copper-nickel mine to apply<br />

for permits in Minnesota.”<br />

Minnesota Republican legislative leaders hailed the DNR’s<br />

decision.<br />

“This new mine will create many good-paying jobs in Northeastern<br />

Minnesota and provide a real boost to the state’s<br />

economy,” House Speaker Kurt Daudt, a Republican from<br />

Crown, said in a statement.<br />

The project would cost an estimated $945 million to construct.<br />

PolyMet said site preparation and rehabilitation of the<br />

former LTV Steel plant for a copper-nickel processing plant<br />

will continue through the winter and early spring. The company<br />

said the bulk of work is expected to start in the 2019<br />

construction season and last about 24 to 30 months.<br />

Forging Ahead with Advanced HDPE<br />

Cooling Towers<br />

HDPE Cooling Towers from Delta Cooling are impervious to corrosive<br />

environments, require less downtime for repair or replacement, and lower<br />

amounts of water treatment chemicals.<br />

The forging industry has achieved an impressive place in the<br />

North American industrial economy by producing components<br />

with unique benefits that are difficult to duplicate.<br />

Forging, a manufacturing process of shaping metal by applying<br />

a variety of powerful compressive forces to it, is known<br />

for producing parts that feature excellent fracture toughness,<br />

ductility, as wells as both impact- and fatigue-strength.<br />

However, delivering on those attributes also requires dealing<br />

with the extremely high heat generated during the forging<br />

process, which can reach up to 1,150 degrees C (2,102 F).<br />

For Patriot Forge, a Canadian supplier of custom open die<br />

and rolled ring forgings, controlling those high temperature<br />

hinges on dependable cooling tower technology.<br />

Frequently used for industrial applications such as refineries,<br />

metal foundries and manufacturing plants, cooling towers<br />

remove heat from cooling system water and exhaust it into<br />

the atmosphere.<br />

Needing an Advanced Solution<br />

With plants in Branford and Paris, Ontario, Patriot Forge<br />

produces products in a variety of materials ranging from<br />

carbon, alloy, stainless steel, nickel-based alloys and aluminum.<br />

Producing for demanding industries such as power<br />

generation, petrochemical, heavy-equipment manufacturers,<br />

military and aerospace requires consistent quality, including<br />

the vital hardness characteristics of forgings ranging from 5<br />

lbs. to 50 tons.<br />

According to Derek Hynes, Senior Mechanical Engineer at<br />

Patriot Forge, three years ago, the company decided to begin<br />

the process up replacing its aging, multi-use cooling tower,<br />

located at Building One of its Branford plant.<br />

“The tower we were replacing was a traditional steel model<br />

that was rotting out,” Hynes explains. “Also, metal models<br />

tend to rust and corrode, which usually leads to plugging the<br />

water flow — and that can interfere with cooling capacity.”<br />

This cooling tower is used to expel heat from the Building<br />

One quench system, a 42,000-gallon water tank into which<br />

parts are submerged in water or polymer baths in order to<br />

achieve the desired hardness.<br />

provide reliable, trouble-free operation for a longer period<br />

of time.<br />

The team ultimately chose a cooling tower constructed on<br />

HDPE (high-density polyethylene) manufactured by Delta<br />

Cooling Towers (www.deltacooling.com), the company that<br />

originally developed the engineered plastic technology.<br />

HDPE cooling towers are impervious to corrosive environments,<br />

and require lower amounts of expensive water<br />

treatment chemicals as well as less downtime for repair or<br />

replacement. The same manufacturer also offers models with<br />

energy-saving features such as direct drive fan motors that<br />

can drastically reduce electricity costs.<br />

“We saw that this was a polymer-based tower that was<br />

UV-protected, and included a 20-year warranty, so we were<br />

convinced that it would offer long-term dependable service,”<br />

Hynes says.<br />

Supporting Multiple Systems<br />

After the initial HDPE tower was successfully installed and<br />

exceeded expectations, Patriot Forge decided to acquire a<br />

second HDPE cooling tower to support hydraulic cooling for<br />

their new 5,000-ton hydraulic press, rail-bound manipulator,<br />

and hydraulic ring roller.<br />

Forging is the process of shaping metal by applying a variety of powerful<br />

compressive forces to workpieces that are heated to around 1,150 degrees<br />

C (2,102 F).<br />

“This new tower needed to support multiple systems within<br />

Forging is famous for producing parts that feature excellent fracture toughness,<br />

ductility, as wells as both impact- and fatigue-strength.<br />

the Building One,” explains Hynes. “This included cooling the<br />

water that flowed through a heat exchanger used to draw<br />

heat off the hydraulic systems of three large pieces of production<br />

equipment, including the 5,000-ton press that plays<br />

a primary role in the forging processes of the plant.”<br />

“Essentially, all three machines are cycling the water that<br />

flows through their hot hydraulic heat exchangers and then<br />

through this cooling tower. This enables us to keep the hydraulic<br />

fluids at a stable 110 degrees (F).”<br />

Extending the Benefits<br />

Then earlier this year, Patriot Forge acquired an additional<br />

twin cell HDPE cooling tower to help cool the quench tanks<br />

that are part of the company’s heat treat system in Building<br />

Two.<br />

“Both of the quench tanks are 105,000 gallons, and we use<br />

the cooling towers to help maintain a heat level of approximately<br />

100 degrees (F)”, Hynes says.<br />

The cooling towers that Patriot Forge selected for this building<br />

were the same design as the one selected as a replacement<br />

in Building One, Delta TM Series Induced Draft models.<br />

One of the unique benefits of the TM Series towers is the<br />

ability to configure them in combination of up to six units<br />

with cooling capacity from 250 to 2,500 cooling tons. This<br />

modular design gives companies the opportunity to conve-<br />

report earlier this year suggesting that PFAS might be more<br />

hazardous than previously thought. Exposure to the compound<br />

has been linked to an increased risk of cancer and the<br />

compound can affect development in children.<br />

Patriot Forge recently upgraded four cooling towers — supporting multiple systems throughout its plant in Canada — with HDPE Technology.<br />

niently add cooling towers as their processing grows. The<br />

new, cooling towers installed at Building Two are installed in<br />

a two-cell configuration with combined cooling capacity of<br />

836 cooling tons.<br />

“We decided on this size and configuration because the<br />

quench tanks in Building Two are much larger,” says Hynes.<br />

“So, there is a lot more water you have to process through<br />

the towers.”<br />

He notes that installation of the factory-assembled cooling<br />

towers was relatively easy. “The HDPE plastic towers are<br />

lighter, so we were able to use a smaller crane to install<br />

them, which was much more convenient than having to deal<br />

with larger, bulkier cranes.”<br />

Hynes says the towers feature vibration sensors on all fans,<br />

which eliminates the need to climb the towers in order to<br />

check out the operating performance of the fans, a benefit<br />

that Hynes feels is particularly appealing because one of the<br />

towers tops out at a daunting 65 ft. — “a long way up.”<br />

JUNEAU, Alaska (AP) — The state is offering safe drinking<br />

water to households in a southeast Alaska town after a toxic<br />

substance was discovered in groundwater.<br />

A dozen private wells in Gustavus qualified to receive<br />

shipped-in jugs of water from the state following the discovery<br />

of a chemical compound known as PFAS, Alaska’s Energy<br />

Desk reported Oct. 31.<br />

The substance is found in foam used to suppress oil fires. It<br />

can seep into the ground and cause contamination.<br />

The Centers for Disease Control and Prevention released a<br />

The state Department of Transportation tested wells over the<br />

summer near the Gustavus airport.<br />

Gustavus resident Kelly McLaughlin said she learned of the<br />

testing and persuaded the state to test her well. The results<br />

last month showed the well contained twice as much of the<br />

contaminant as the federal government advises for health.<br />

“You don’t think the water you’ve been drinking and assume<br />

is safe is poison,” McLaughlin said. “That’s not a thought<br />

that crossed my mind ever. I wasn’t prepared for the results<br />

to be that bad.”<br />

The state Department of Transportation plans to bring in an<br />

engineer to develop some long-term solutions.<br />

Gustavus is a city of 550 on the north shore of Icy Passage.<br />

The city is 48 miles (77 kilometers) northwest of Juneau. It<br />

is surrounded by Glacier Bay National Park and Preserve on<br />

three sides.<br />

“This was nobody’s fault. As far as I know, nobody knew how<br />

bad these chemicals were,” McLaughlin said. “Nobody knew<br />

how far they would travel. The DOT did not intentionally<br />

poison the people in Gustavus. But it happened.”<br />

Canadian Firm Seeks Arkansas Pilot<br />

Plant to Extract Lithium By Kyle Massey<br />

EL DORADO, Ark. (AP) — Standard Lithium Ltd., the Canadian<br />

company with big plans to tap south Arkansas’ underground<br />

brine stream to extract battery-grade lithium, is<br />

ramping up testing at a pilot crystallization plant in British<br />

Columbia and gaining provisional approval for a pilot extraction<br />

operation west of El Dorado that could be in place<br />

as early as late February.<br />

Standard, of Vancouver, has completed a plant to test its proprietary<br />

selective crystallization process, designed to refine<br />

battery-quality lithium from a solution extracted from brine,<br />

in partnership with Saltworks Technologies Inc. of Richmond,<br />

British Columbia.<br />

The technology in the pilot plant, if successful, could end up<br />

refining extracts pulled from South Arkansas brine, which<br />

was found to hold strong concentration of lithium carbonate<br />

in tests of saltwater from two previously drilled oil and gas<br />

wells in south Arkansas.<br />

Lithium, a valuable element used in everything from cellphone<br />

and laptop batteries to the systems of electric automobiles,<br />

could be a boon for Arkansas’ economy if the publicly<br />

traded Canadian company, which has partnered in brine<br />

leases near El Dorado and Magnolia, can prove its ability to<br />

refine battery-grade lithium at an industrial scale.<br />

The prototype pilot plant, which is undergoing commissioning<br />

for operation now, will be operated initially at Saltworks<br />

Technologies’ Richmond facility. Standard Lithium CEO<br />

Robert Mintak said the ultimate goal is to extract the lithium<br />

and then refine it, all in Arkansas.<br />

He added that the Arkansas Oil & Gas Commission is giving<br />

his company a chance to prove its process by operating the<br />

pilot extraction plant with a waiver.<br />

“The purpose is to prove that we can extract lithium with our<br />

selective extraction plan, and then produce battery-grade<br />

material in Arkansas,” Mintak told Arkansas Business in<br />

a recent telephone conversation. “The purpose is to have<br />

everything in Arkansas,” with the pilot extraction technology<br />

in place in the first half of 2019.<br />

“That plant is going to be moved to Arkansas probably<br />

in late February or early March,” Mintak said. “That’s the<br />

extraction pilot plant. The pilot plant in Richmond, on the<br />

other hand, is a plant that converts the extracted lithium<br />

solution into a final battery material. We’ve developed our<br />

own process to crystallize lithium carbonate, and we feel our<br />

own process may be an improvement, but we’re going to be<br />

working with some other industry partners that have crystallizers<br />

in use around the world. We’ll be testing our own<br />

process along with others.”<br />

Saltworks CEO and chief engineer Ben Sparrow said in a<br />

statement that if Standard Lithium likes the results it sees at<br />

the pilot plant in Canada, “we are ready to rapidly deliver a<br />

mobile fully continuous plant and support Standard Lithium<br />

to commercialize this high-potential technology.”<br />

Mintak has cited Arkansas’ regulatory environment, as well<br />

as its vast supply of mineral-dense brine, as factors that led<br />

Standard Lithium to Arkansas.<br />

“We had a meeting with the Oil & Gas Commission a week<br />

ago and gave a presentation to proceed with a waiver,”<br />

Mintak said in early November. “There is not a royalty set as<br />

yet for lithium in Arkansas, so they’re allowing us to prove<br />

the extraction process works as we operate the pilot plant.<br />

Then as we get data on that we’ll start working with them<br />

on the royalty regime.”<br />

Standard Lithium is listed on Canada’s TSC Venture exchange<br />

under the trading symbol SLL and on the OTCQX under the<br />

symbol STLHF. It is also traded in Europe on the Frankfurt<br />

Stock Exchange.<br />

Officials: Saline County Dam on Verge<br />

of Collapse<br />

HENSLEY, Ark. (AP) — A dam at a central Arkansas lake has<br />

many safety issues that indicate a lack of maintenance and<br />

could cause the structure to collapse, according to state<br />

officials.<br />

Arkansas Natural Resources Commission engineer Stephen<br />

Smedley inspected the Lake Sandy dam this year and identified<br />

needed repairs that could cost at least a half million<br />

dollars, the Arkansas Democrat-Gazette reported.<br />

The commission warned nearby homeowners of issues that<br />

could cause the dam to break, emptying the Saline County<br />

lake.<br />

“The internal erosion and voids could cause the dam to collapse,”<br />

a letter to residents stated. “The many slides, slumps,<br />

erosion channels, large trees, rodent activity and animal<br />

burrows on the upstream and downstream slope are very<br />

concerning and indicate a lack of maintenance.”<br />

Property owners worry they’ll be liable for damages if the<br />

unregulated dam fails.<br />

The Lake Sandy Property Owners Association acquired the<br />

dam in 1992 and is responsible for its maintenance. The<br />

association had its last meeting in the mid- to late-1990s, and<br />

residents believe that’s when dam maintenance stopped.<br />

If dues had been collected and used to maintain the dam,<br />

some of the structure’s larger problems could’ve been prevented,<br />

Smedley said.<br />

But Mike Oglesby, who lives in a camper by the lake, estimated<br />

that residents haven’t paid dues to the association for at<br />

least 20 years.<br />

Oglesby didn’t know anything about the dam until this year,<br />

and neither did state dam safety officials. Arkansas has data<br />

on 410 regulated dams and nearly 900 more for informational<br />

purposes, but no documentation on Lake Sandy. The Lake<br />

Sandy dam and its ownership aren’t known to the National<br />

Inventory of Dams, either.<br />

“It’s not a matter that the dam will break,” Oglesby said. “It’s<br />

when it will break.”<br />

Tests Find Contamination in<br />

Indianapolis Suburb<br />

FRANKLIN, Ind. (AP) — New test results confirm that groundwater<br />

and sewer vapors in an Indianapolis suburb have<br />

cancer-causing chemicals at levels that exceed the Indiana<br />

environmental agency’s safe limits.<br />

Environmental firm EnviroForensics found high levels of<br />

trichloroethylene and tetrachloroethylene in Franklin, The<br />

Indianapolis Star reported.<br />

TCE and PCE are found in household items, such as cleaning<br />

solutions, but can have harmful health impacts in high concentrations,<br />

according to the Centers for Disease Control and<br />

Prevention.<br />

The U.S. Environmental Protection Agency told city officials<br />

that it’s monitoring the site formerly used by Amphenol, an<br />

electronics manufacturer. Franklin Mayor Steve Barnett said<br />

the city hired the consulting firm to test if chemicals were<br />

leaving the site.<br />

“We’re all trying to get the same answers and get to the<br />

bottoms of things,” he said. “I told them they need to come<br />

prove to me that everything is fine, and I won’t be convinced<br />

until they’ve done all the testing possible and show me the<br />

results.”<br />

EnviroForensics Chief Executive Steve Henshaw said the tests<br />

results show that pollution wasn’t confined. “Clearly they<br />

have not fully remediated or cleaned up the source,” he said.<br />

The Environmental Protection Agency is expanding its<br />

contamination testing area near the manufacturing facility,<br />

The Daily Journal reported. The federal government has also<br />

begun installing air-filtering systems in some residences.<br />

Henshaw said the property’s technology is dated and ineffective.<br />

“This is a classic example of a site that is put on autopilot and<br />

seems to have fallen through the cracks,” he said. “As a result,<br />

follow-up work wasn’t being checked and they assumed<br />

the cleanup was working and it wasn’t.”<br />

Co-op Program Teaches Students<br />

Valuable Trade Skills By Ethan Forman<br />

DANVERS, Mass. (AP) — Five years from now, a plumber will<br />

be more important than an attorney.<br />

That’s what Cranney Companies President Brian Cranney<br />

joked last month, before a North Shore Chamber of Commerce<br />

breakfast in Salem.<br />

His point? There aren’t enough plumbers to go around.<br />

Cranney said he doesn’t have enough workers to staff all of<br />

the service trucks for his Danvers company, which provides<br />

plumbing, heating, cooling and electrical services, among<br />

others.<br />

But there’s a solution. Cranney has turned to Essex Tech’s<br />

co-op program, to help train and recruit tomorrow’s plumbers,<br />

electricians and HVAC technicians. His company is one<br />

of several in the region that rely on the technical school for<br />

future workers.<br />

“It’s the main artery of my business on the North Shore and<br />

how I’ve been able to grow it,” Cranney said. Many of the<br />

Cranney Companies’ Brian Cranney has turned to Essex Tech’s co-op program<br />

to help train and recruit tomorrow’s plumbers, electricians and HVAC<br />

technicians. (Credit: Wikimedia Commons/John Phelan)<br />

leaders in his company today were first hired as high school<br />

juniors. They went on to get their various licenses and work<br />

for Cranney full-time.<br />

Essex Tech’s co-op program places juniors and seniors with<br />

businesses in various fields such as plumbing, electrical,<br />

advanced manufacturing, culinary arts and construction, to<br />

name a few.<br />

“It’s the culmination of a student’s program, really,” said<br />

Lisa Berube, Essex Tech’s cooperative education coordinator.<br />

“They come here and they get the skills and the training to<br />

be able to enter the workforce, so the cooperative education<br />

program is that next piece, if you will, that gets them into<br />

the workforce out of the school setting to apply those skills.”<br />

The students work in a co-op job for one week, then take<br />

high-school academic courses the following week, off and on<br />

throughout the school year. They often earn more than the<br />

minimum wage.<br />

Culinary arts sophomore Emma Bedard, 15, of Salem, said<br />

she is looking forward to joining the co-op program next<br />

year. Bedard, who aspires to be a baker, was working at the<br />

school’s Maple Street Bistro last month.<br />

“I think it’s amazing because you can actually get the skills<br />

and everything you need and it helps you get jobs going out<br />

of high school,” she said.<br />

“I think it’s pretty close experience to the real world,” said<br />

sophomore Jack Donovan, 16, of Peabody, about what he’s<br />

doing in the school’s advanced manufacturing shop. Donovan<br />

said he had been thinking about a future in mechanical<br />

engineering, but the skills he is learning now are closely<br />

related.<br />

“I also like using my hands and getting dirty. It’s just such a<br />

fun shop to learn in,” said Donovan, who plans to work in a<br />

co-op job next year.<br />

The demand to attend Essex Tech has skyrocketed.<br />

The school has gone from under 1,200 students in 2014 to<br />

1,421 students in 25 career and technical programs. Of the<br />

1,200 applications it gets each year, it only has 375 slots.<br />

The regional school is the result of a merger of the former<br />

North Shore Tech, Essex Aggie and Peabody high school<br />

vocational programs. While it opened several years ago,<br />

Superintendent-Director Heidi Riccio, the guest speaker before<br />

the North Shore Chamber last month, said the school is<br />

already running out of space in some trade areas, including<br />

plumbing.<br />

Riccio said the school depends on business leaders like Cranney<br />

to show the school what it needs to train its students.<br />

“We also look at them as partners,” Riccio said. “They not<br />

only hire our students, but we are also hoping to start an<br />

adult education program to train existing workforce within<br />

that industry, as well as future workforce.”<br />

The construction trades are booming, and that means Essex<br />

Tech co-op students are in demand, said Bonnie Carr, the<br />

school’s community relations and partnership coordinator,<br />

who also undertakes workforce development.<br />

“The kids go out, they work. They (employers) keep them<br />

through the summer. They work all of their senior year, and<br />

then they pick them up after graduation,” Carr said.<br />

Carr said there is a demand for students in culinary arts, given<br />

Salem’s restaurant boom. There is also a demand for those<br />

studying in health care fields. Last year, North Shore Medical<br />

Center took six students who worked in various areas of the<br />

hospital, including the emergency room.<br />

“Our high school nursing students,” Riccio said, “were working<br />

alongside physicians, emergency medical technicians,<br />

RNs.”<br />

Last month, Essex Tech’s plumbing shop was filled with the<br />

sounds of banging as students worked on projects in tall,<br />

plywood booths.<br />

Riccio said the program has expanded to the point it ran out<br />

of space for booths. So, the students built more.<br />

Jim Russell, the grade 11 and grade <strong>12</strong> plumbing instructor, is<br />

in charge of connecting students with North Shore plumbing<br />

and heating companies. He said his students are in “huge”<br />

demand.<br />

“You know, the kids with the skills here you can’t get this<br />

education even if you are an adult. This doesn’t exist,”<br />

Russell said. “It only exists here, and with only 15 to 18 kids<br />

per class, you know, they have skills that you can’t get at any<br />

other place.<br />

“They know how to do everything,” Russell said. “So, the<br />

employers like that because they can train them the way<br />

they want them but they have the basic, raw talent to work<br />

with.”<br />

Russell noted there is a shortage of plumbers. Their average<br />

age in Massachusetts is 55. But the base wage of an experienced<br />

union plumber is approximately $55 an hour, Russell<br />

said. Benefits can boost this wage to more than $80 an hour.<br />

“These kids are going to find themselves in a really good job<br />

market,” said plumbing instructor Karl Jacobson. The connection<br />

to local plumbing businesses through the co-op program<br />

is vital. Many Essex Tech graduates stay with the company<br />

they worked for in high school.<br />

In the school’s advanced manufacturing shop, where future<br />

machinists work on high-tech, precision manufacturing<br />

lathes and mills, Riccio noted wages for machinists range<br />

from $16 to $100 an hour. Some students are able to work<br />

weekends making $30 to $40 an hour.<br />

Instructor Jack Fraizer said from what the students are<br />

learning, they can go right into a shop after they graduate.<br />

And they are in demand, now, because many people stopped<br />

going into the field when work moved overseas.<br />

“We can’t even give them enough students because we don’t<br />

have enough to give to them,” Fraizer said. “Right now the<br />

demand for just certain companies I know of ... One just said<br />

they need 300 people within the next year.”<br />

COMPLETE CHILLER upgrade<br />

Fan pumps at the Chicago Marriott Downtown<br />

Magnificent Mile. The chiller system services the<br />

hotel’s 970,000 sq. ft.<br />

The Chicago Marriott Downtown Magnificent Mile hotel<br />

occupies an enviable location along the city’s Magnificent<br />

Mile, offering views of the surrounding city and Lake Michigan.<br />

To help the 970,000-square-foot hotel retain its status<br />

as a downtown destination for travelers, management is in<br />

the process of completing a range of upgrades, including an<br />

aesthetic facelift throughout its 1,200 rooms and suites.<br />

Keeping pace with guest-facing enhancements, the hotel is<br />

giving some much-needed attention to its major mechanical<br />

systems — most recently with the installation of new chiller<br />

equipment. As Marriott learned, choosing energy efficiency<br />

equipment not only lowers operating costs but also can earn<br />

incentives from the ComEd Energy Efficiency Program. Additionally,<br />

the ComEd Energy Efficiency program offers a variety<br />

of options, including direct incentives, to help customers<br />

pay for these improvements.<br />

Setting Sights on Improvements<br />

For more than 40 years, the Chicago Marriott Downtown<br />

Magnificent Mile had relied on its original mechanical equipment<br />

to keep guests comfortable year round. In particular,<br />

two 1,200-ton chillers worked in concert with a cooling tower<br />

on the roof to keep the hotel’s guest rooms and suites air<br />

conditioned during the hottest months of the year. Though<br />

still functioning, that original equipment was struggling<br />

to keep up with the demand. According to Ty Sanders, the<br />

hotel’s director of engineering, the chillers were beyond the<br />

end of their useful lives, and it was time to explore options<br />

to bring the system up to date.<br />

Another view of a fan pump installed as part of<br />

The chillers at the Chicago Marriott Downtown Magnificent<br />

Mile hotel were located in one of the least accessible<br />

parts of the building. The new chillers had to be disassembled<br />

and brought through the elevator shaft.<br />

sustainable design, completed a master survey of the hotel.<br />

“All the equipment was doing its best, but it was coming up<br />

against age and efficiency problems,” said Eric Rosenberg, a<br />

project manager at G/BA. “Reliability was always in the back<br />

of everyone’s mind. Marriott didn’t want the equipment to<br />

fail one day. So we helped them devise a plan for making<br />

upgrades.”<br />

G/BA presented Marriott with a report summarizing the<br />

condition of major equipment throughout the hotel and<br />

suggested ways to move forward while saving energy and<br />

money. The report provided a framework to help the hotel’s<br />

ownership to weigh funding, capital planning and anticipated<br />

operational disruptions that could play a role in project<br />

planning.<br />

While modernizing the hotel’s interior spaces, Marriott management<br />

decided to replace the chillers during an upcoming<br />

heating season. The upgrade process involved competitive<br />

bidding among Chicago-area contractors. In the end, Marriott<br />

selected Mechanical Incorporated as the project’s general<br />

contractor.<br />

“We faced some highly-respected competition during this<br />

process. I specifically put together a team for the build out of<br />

this job, and since we’ve worked together for 25 years, it was<br />

only right,” said Kirk Jurinek, a senior project manager at<br />

Mechanical Incorporated. “We’ve probably installed 60 to 70<br />

chillers, so I think that was refreshing to both Marriott and<br />

Grumman/Butkus Associates.”<br />

Bringing in Energy Efficiency<br />

Once Mechanical Incorporated was chosen in 2017, construction<br />

could begin. One of the first and most important decisions<br />

made to improve energy efficiency was to downsize the<br />

two existing 1,200-ton chillers and replace them with three<br />

800-ton chillers.<br />

Adding a third chiller gave Marriott greater flexibility of<br />

temperature control throughout the property, and provided<br />

redundancy in case a backup should be needed.<br />

“They really only needed to run both chillers at full capacity<br />

a couple days of the year,” said Rosenberg at G/BA. “But because<br />

of the chiller size, even on a mild day, they might have<br />

needed to use both of them. Smaller equipment allows for<br />

greater flexibility in switching from one to another. It’s just a<br />

better way to run the building without relying on two older<br />

pieces of equipment.”<br />

Jurinek’s team at Mechanical Incorporated designed a<br />

three-dimensional building information model to show<br />

exactly how the new equipment would fit into Marriott’s existing<br />

layout. The model enabled contractors, engineers and<br />

Marriott staff to envision the completed installation before<br />

any equipment even arrived.<br />

“The modeling really helped with the efficiency of the<br />

installation,” Jurinek said. “Because Marriott’s engineers<br />

know their building so well, they were able to offer helpful<br />

logistical insight throughout the project.”<br />

Construction began in October 2017 to coincide with the<br />

hotel’s heating season. Marriott’s Sanders said this step minimized<br />

any impacts on operations, as the hotel primarily runs<br />

boilers during the colder months.<br />

“We also had been under renovation for four years, so we<br />

were used to cycling materials in and out of the building,”<br />

he said.<br />

Jurinek agreed that cooler outdoor temperatures made fall a<br />

prime time to start the chiller replacement. However, he described<br />

a few additional obstacles that crews worked around<br />

to prevent any disruption to hotel guests and employees.<br />

“The chillers are tucked below the hotel’s loading dock in<br />

one of the least accessible parts of the building,” he said.<br />

“Though the new chillers are smaller than the previous<br />

equipment, they still had to be completely disassembled to<br />

be brought in through the elevator shaft.”<br />

To coordinate all the moving pieces, Mechanical Incorporated<br />

oversaw the various trade professionals to complete<br />

the installation on time and on schedule. Grumman Butkus<br />

worked diligently to help Marriott secure thousands of<br />

dollars in incentives through the ComEd Energy Efficiency<br />

Program.<br />

Negligible interruption to daily operations confirmed Marriott’s<br />

decision to make this energy efficiency upgrade a<br />

Back view of the fan pumps at the Chicago<br />

Marriott Downtown Magnificent Mile.<br />

priority. The availability of incentives from ComEd made the<br />

chiller replacement a no-brainer.<br />

“The rebates were a nice bonus to move the project forward,”<br />

said Sanders. “They made the approval process go<br />

smoothly.”<br />

Marriott received over $200,000 in incentives for its chiller<br />

replacement project because the team chose qualifying<br />

high-efficiency equipment.<br />

“The ComEd program is particularly nice because it has<br />

prescriptive options where you can almost check the box. If<br />

you install this piece of equipment, you’ll get this incentive<br />

amount,” Rosenberg said.<br />

Everything from high-efficiency heating and cooling equipment<br />

to LED lighting and variable frequency drives for motors<br />

and fans can qualify for incentives.<br />

“And the utility also offers custom options if you’re doing<br />

something a little more involved,” Rosenberg added. “If you<br />

have an idea that reduces electricity use, the custom program<br />

is there to provide incentives to move the project forward.”<br />

ComEd’s custom incentives are based on the actual kilowatt-hour<br />

savings achieved by a project in the first year after<br />

it is completed. Qualifying projects can earn incentives up to<br />

$0.07 per kWh saved in the first year.<br />

“It’s a great way to get people to think beyond the cheapest<br />

approach,” said Rosenberg. “With greater energy efficiency<br />

and better products moving forward, customers can save<br />

even more on energy costs over time.”<br />

Recognizing Multiple Benefits<br />

Following a seamless approval and installation process, Sanders<br />

said the hotel has achieved numerous benefits from the<br />

new cooling equipment.<br />

“Our energy savings from the chillers add up to approximately<br />

$100,000 per year,” he said. “Our guests and employees<br />

are more comfortable. From a maintenance perspective,<br />

we’ve received fewer service calls, and the new equipment<br />

allows us to operate more efficiently during periods between<br />

the heating and cooling seasons.”<br />

The addition of the third chiller also gives Marriott more<br />

flexibility to control the temperature in spaces across the<br />

hotel. “With the old equipment, if they had to shut down<br />

one chiller during the summer, they could run into issues,”<br />

Jurinek said. “Now they have the luxury of energy savings,<br />

with greater options for operations and maintenance.”<br />

Investments in energy efficiency also can yield benefits that<br />

last for years to come. “People used to look at their energy<br />

bills and say, ‘We’ve got to do something to lower them,’”<br />

Rosenberg added. “Now, many people think beyond that<br />

and try to make things better not only for themselves, but<br />

also for future generations. There is a nice ripple effect with<br />

reduced energy consumption.”<br />

Building for the Future<br />

Sanders described Marriott’s chiller replacement project as a<br />

complete success and encourages other businesses to pursue<br />

energy-saving options. “Not only will these upgrades help<br />

preserve our natural resources, but the cost savings are an<br />

immediate benefit to our ownership,” he said.<br />

Rosenberg applauds Marriott’s leadership and approach in<br />

replacing outdated equipment before experiencing major<br />

issues from a failed system. He advises other businesses to<br />

take a similar route.<br />

“If you can plan for upgrades and get started before it<br />

becomes an urgent need, you’ll be able to find the best longterm<br />

solutions for your business,” Rosenberg said. “With<br />

incentives offered through the ComEd Energy Efficiency<br />

Program, you can save even more on the upfront cost. Now is<br />

a great time to invest in improving your energy efficiency.”<br />

Michigan Officials Urge Bridge<br />

Authority to OK Pipeline Deal By John Flesher<br />

TRAVERSE CITY, Mich. (AP) — Michigan officials took another<br />

step Nov. 8 toward construction of an oil pipeline tunnel<br />

beneath the channel that links Lakes Huron and Michigan<br />

by asking the Mackinac Bridge Authority to accept oversight<br />

responsibility for the proposed structure.<br />

Department of Natural Resources Director Keith Creagh and<br />

two consultants pitched the plan to the bridge authority.<br />

No vote was taken but the authority heard dozens of public<br />

comments, most opposed to the project as potentially posing<br />

a risk to the Straits of Mackinac and the area’s fishing and<br />

tourism industries.<br />

“Don’t ram this down our throats. Don’t rush things,” said<br />

Bay Mills Indian Community chairman Bryan Newland, who<br />

added that the project would violate native fishing treaty<br />

rights.<br />

Gov. Rick Snyder’s administration reached a deal last month<br />

with Enbridge Inc. to drill the tunnel beneath the Straits of<br />

Mackinac over 7 to 10 years at a cost of up to $500 million,<br />

which the company would pay. The bridge authority would<br />

assume ownership after completion and lease the tunnel<br />

back to Enbridge for 99 years.<br />

It would replace an underwater segment of Enbridge’s Line<br />

5, which carries about 23 million gallons of oil and natural<br />

gas liquids daily. Environmentalists are pushing to decommission<br />

the twin lines, which have been in place since 1953,<br />

while the company says they’re in good condition.<br />

A crucial part of Snyder’s plan is putting the bridge authority<br />

in charge of the tunnel, even though the authority’s only responsibility<br />

since its founding has been managing the 5-milelong<br />

bridge linking Michigan’s Upper and Lower Peninsulas.<br />

Michael Mooney, a Colorado School of Mines expert on<br />

tunnel design and consultant for the state, said the tunnel<br />

proposal is sound and would provide extra protection by<br />

encasing the new pipeline in concrete.<br />

“There is virtually no way for product to leak out of this<br />

Wind Towers Coming Down Under<br />

Court Orders<br />

FAIRBANK, Iowa (AP) — Developers are taking down three<br />

northeast Iowa wind turbine towers under court orders.<br />

The first was removed last week and the second is going<br />

down this week, the Waterloo-Cedar Falls Courier reported.<br />

The 450-foot-tall (137 meters) towers were erected in 2015<br />

just east of Fairbank in Fayette County. They drew opposition<br />

from housing developers and neighboring homeowners who<br />

believed the towers would be detrimental to the city.<br />

Fairbank City Council members filed a lawsuit that said the<br />

county issued construction permits without following zoning<br />

ordinances. Woods Construction, which had been developing<br />

a residential subdivision near the wind farm, filed a separate<br />

suit.<br />

A judge sided with the city in 2016, and the Iowa Supreme<br />

Court upheld that ruling. The turbines must be removed by<br />

Dec. 9.<br />

Resident Joyce Kerns said she’s happy with the decision to<br />

remove the turbines.<br />

“I’m thrilled,” Kerns said. “The constant whoosh, whoosh,<br />

whoosh sound they make is nonstop, and the shadow effect<br />

was like I was back in the ’70s with the disco strobe light.”<br />

The developers — Mason Wind, Dante Wind 6, Galileo Wind<br />

1 and Venus Wind 4 — are still appealing in the courts. The<br />

companies requested a variance from the Fayette County<br />

Board of Adjustment to allow the turbines to remain. The<br />

companies are appealing the board’s June decision to deny<br />

the request.<br />

“While we continue to seek other avenues to allow those investments<br />

in wind energy to remain in Fayette County, until<br />

we get a different ruling the wind LLCs will continue to fully<br />

comply with the order currently in effect,” said Bret Dublinske,<br />

an attorney for the companies.<br />

Mortenson Completes Enclosure of<br />

Halas Hall Addition for NFL’s Chicago<br />

Bears<br />

The current project follows the 2013 Halas Hall renovation<br />

led by Mortenson that upgraded the Bears’ business offices<br />

and added a state-of-the art media and broadcast center,<br />

viewing suite and cafeteria. One of the top three national<br />

sports builders, Mortenson has completed more than $8<br />

billion in professional and college sports facilities in the past<br />

decade.<br />

“We want to use every advantage to help our players and<br />

coaches succeed, and a first-class training and recovery center<br />

is key to our team development plan,” said Bears President<br />

and CEO Ted Phillips. “Mortenson has worked closely<br />

with us to complete the expansion and remodeling of Halas<br />

Hall as quickly as possible, even as the team and business<br />

office staff continue using the building.”<br />

Mortenson is on track to complete its expansion and renovation of Halas<br />

Hall before the start of next year’s football season.<br />

Chicago — Mortenson has completed the enclosure of the<br />

major new addition to Halas Hall, putting it on track to complete<br />

the expansion and renovation of the home of the Chicago<br />

Bears National League Football team before the start<br />

of next year’s football season. The modernization, including<br />

the 162,500 square foot addition that more than doubles<br />

the size of the Bears’ headquarters, will deliver an expansive,<br />

state-of-the-art training center for players, coaches and the<br />

entire football operation.<br />

“The Chicago Bears are investing for now and the future<br />

with this world-class facility. The Bears are providing all of<br />

the tools, equipment, technology and amenities to help its<br />

players and coaches prepare and perform at their best,” said<br />

Lori Leber, Mortenson design phase executive who is overseeing<br />

the project.<br />

Improvements include:<br />

• 13,000 square foot indoor turf field with projection screen,<br />

virtual reality room and adjacent classrooms for learning<br />

and practicing plays<br />

• Expanding the weight room by 2,000 square feet<br />

• Doubling the size of the equipment room, recovery space,<br />

and nutrition and fuel station<br />

• Building new locker rooms, players lounge<br />

• Expanding coaches’ offices, position meeting rooms, and<br />

draft room<br />

• Increasing by four times the hydrotherapy and sports medicine<br />

space<br />

Meeting the ambitious construction schedule while the<br />

building is occupied requires careful staging and coordination<br />

of work supported by innovative Lean construction<br />

techniques. The Bears organization brought in Mortenson<br />

from the start, so the builder could play a key role in informing<br />

the building plan, design and layout. Mortenson<br />

worked with the design team and the Bears to optimize the<br />

floor plan so that it would provide the least disruption to the<br />

Bears’ ongoing operations. For example, Mortenson advised<br />

on the ideal location for the demolition of the north addition<br />

to occur. This allowed for optimal construction phasing<br />

which made it possible for the Bears to remain in their<br />

existing locker room until the first phase of construction was<br />

completed. Mortenson also used prefabricated wall panels<br />

to reduce installation time, enabling the team to meet the<br />

accelerated construction schedule.<br />

Mortenson and its subcontractors are using the Lean approaches<br />

of 5S and Pull Planning to increase productivity<br />

and safety. 5S, which stands for sort, straighten, shine,<br />

standardize and sustain, makes construction sites cleaner and<br />

more efficient. With Pull Planning, Mortenson and its trade<br />

partners collectively determine the best work sequences and<br />

durations, identify conflicts and develop solutions. These<br />

strategies are especially effective at the Lake Forest, Ill. site,<br />

where the team has minimal space onsite to stage and store<br />

materials and must rely on just-in-time deliveries.<br />

Mortenson broke ground on the addition in March.<br />

Sioux Falls Manages Contaminated<br />

Water From Toxic Foam<br />

SIOUX FALLS, S.D. (AP) — Sioux Falls officials are grappling<br />

with well shutdowns as the extent of the city’s water contamination<br />

from decades of firefighting foam use remains<br />

unclear.<br />

Sioux Falls currently has 19 municipal wells sitting dormant<br />

in the aftermath of innumerable gallons of toxic firefighting<br />

foam that contaminated the grounds of the city airport nearly<br />

50 years ago, the Rapid City Journal reported. Chemicals<br />

linked to cancer and other health issues were found to have<br />

contaminated 15 municipal wells, including 10 that have<br />

concentrations above what the Environmental Protection<br />

Agency deems safe.<br />

About 28 percent of the city’s water production from the Big<br />

Sioux aquifer is shut down.<br />

The South Dakota Air National Guard and the Sioux Falls<br />

Fire Department both used the toxic firefighting foam for<br />

many years near the airport, which led to the contamination<br />

of the city’s drinking water. But the scope of the issue is still<br />

unknown.<br />

“We really haven’t determined the extent of release yet,”<br />

said Capt. Jessica Bak, a public affairs officer with the Air<br />

Guard at the Sioux Falls Regional Airport.<br />

In 2013, the city’s water purification plant found chemicals<br />

from firefighting foam, known as per and polyfluoroalkyl<br />

substances (PFAS), at levels below the EPA’s health advisory<br />

level. The level of exposure beneath the EPA’s threshold<br />

means there aren’t expected adverse health risks.<br />

The city responded to the findings by testing all municipal<br />

wells to identify the source and shutting down every well<br />

where the chemicals were found.<br />

City engineer Tim Stefanich, who oversees the water system,<br />

acknowledged that “there was a little bit of time between”<br />

finding the contamination, determining its source and deciding<br />

to shut off wells. But he said that there was minimal fear<br />

of an immediate health risk with the low levels of exposure.<br />

The city tested for PFAS again in 2014 as part of an EPA-mandated<br />

water sampling program, but didn’t detect any of the<br />

chemicals. The city tested again in 2016, when some low<br />

levels were found.<br />

The city shut off more wells, leading to the 19 wells offline<br />

today. Water leaving the city’s purification plant is now<br />

sampled monthly, and no water samples have contained the<br />

chemicals since 2016.<br />

Stefanich and Trent Lubbers, the city’s utilities operation<br />

administrator, believe the contaminated water situation is<br />

under control.<br />

The city has been purchasing water from the Lewis and Clark<br />

Regional Water system, a nonprofit, wholesale provider of<br />

treated water. But Sioux Falls will likely need a more sustainable<br />

option.<br />

“They have the short term kind of covered,” said Mark<br />

Meyer, drinking water program administrator for the state’s<br />

Department of Environment & Natural Resources. “But as we<br />

march into the future, having 28 percent of their well capacity<br />

offline, the future is going to come sooner than later.”<br />

Apple Offers Range of iPhones, From<br />

$450 to $1,100New Mobile App<br />

This Monday, Oct. 22, <strong>2018</strong>, photo shows from left the iPhone 8, iPhone 8<br />

Plus, and the iPhone XR in New York. The new XR phone has a larger display<br />

and loses the home button to make room for more screen. (AP Photo/<br />

Richard Drew)<br />

NEW YORK (AP) — Apple’s new iPhone XR has most of the<br />

features found in the top-of-the-line iPhone XS Max, but not<br />

its $1,100 price tag. The XR offers the right trade-offs for just<br />

$750.<br />

For something cheaper, you’ll need to look in the iPhone history<br />

bin. Older models are still quite good. If you’re shopping<br />

for a new phone, it pays to think hard about what you really<br />

want and what you’re willing to pay for it. Improvements<br />

over the previous generation tend to be incremental, but can<br />

add up over time — and so do the sums you’ll pay for them.<br />

iPHONE 7 ($449)<br />

The big jump in iPhone cameras came a generation earlier<br />

with the iPhone 6S, when Apple went from 8 megapixels to<br />

<strong>12</strong> megapixels in resolution. With the iPhone 7, the front<br />

camera goes from 5 megapixels to 7 megapixels, so selfies<br />

don’t feel as inferior.<br />

The iPhone 7 is Apple’s first to lose the standard headphone<br />

jack. Headphones go into its Lightning port, which is used<br />

for both charging and data transfer. It’s a pain when you<br />

want to listen to music while recharging the phone. For that,<br />

you need $159 wireless earphones called AirPods. Apple no<br />

longer includes an adapter for standard headphones; one<br />

will set you back $9 if you need it.<br />

iPHONE 7 Plus ($569)<br />

This larger version of the iPhone 7 has a second camera lens<br />

in the back, allowing for twice the magnification without<br />

any degradation in image quality. It also lets the camera<br />

gauge depth and blur backgrounds in portrait shots,<br />

something once limited to full-featured SLR cameras. The<br />

dual-lens camera alone is a good reason to go for a Plus,<br />

though the larger size isn’t a good fit for those with small<br />

hands or small pockets.<br />

iPHONE 8 ($599)<br />

New color filters in the camera produce truer and richer colors,<br />

while a new flash technique tries to light the foreground<br />

and background more evenly. Differences are subtle, though.<br />

The year-old model, similar in size to the iPhone 7, restores a<br />

glass back found in the earliest iPhones. That’s done so you<br />

can charge it on a wireless-charging mat, which also solves<br />

the problem of listening to music while charging. But with<br />

more glass, it’s even more important to get a case and perhaps<br />

a service plan.<br />

iPHONE 8 Plus ($699)<br />

Again, the Plus version has a larger screen and a second lens.<br />

For those shots with blurred backgrounds, a new feature lets<br />

you add filters to mimic studio and other lighting conditions.<br />

iPHONE XR ($749)<br />

The display on Apple’s latest model, which comes out Friday,<br />

lacks the vivid colors, contrast quality and resolution of<br />

the pricier iPhone XS and XS Max. As with the XS models,<br />

though, you’ll still get a display that largely runs from edge<br />

to edge. Gone is most of the surrounding bezel along with<br />

the home button. Many tasks now require swipes rather<br />

than presses. The fingerprint ID sensor is replaced with facial<br />

recognition to unlock the phone. There’s more display than<br />

the regular XS, but the phone itself is also larger — just not<br />

as large as the Max.<br />

The camera continues to improve, with better focus and<br />

low-light capabilities. Many shots now blend four exposures<br />

rather than two for better lighting balance in suboptimal<br />

conditions. The XR doesn’t have the dual-lens camera,<br />

though it can offer some of the blurred-background effect<br />

with software.<br />

iPHONE XS ($999)<br />

As with the iPhone X it replaces, the new XS also has an<br />

edge-to-edge display. The display has about the same surface<br />

area as the iPhone 7 Plus and 8 Plus, while the phone<br />

itself is only slightly larger than the regular iPhone 7 and 8.<br />

Improved display technology means vivid colors and better<br />

contrasts, including black that is black rather than simply<br />

dark. You also get a dual-lens camera.<br />

iPHONE XS Max ($1,099)<br />

This is essentially the “Plus” version of the iPhone XS. The<br />

phone itself is about the size of the Plus, but with more room<br />

for the display. This phone won’t feel big for existing Plus users,<br />

but think twice if you have small hands or small pockets.<br />

While Supplies Last<br />

Apple no longer sells the iPhone SE, which is essentially a<br />

three-year-old iPhone 6S, packed in a body that’s smaller but<br />

thicker than the iPhone 7 and 8. Though the trend in phones<br />

has been to go bigger, some people preferred the smaller<br />

size — and the $350 price tag. You can try to get it from<br />

some wireless carriers and other retailers, at least for now.<br />

All in the Memory<br />

If you get an SE, 7 or 7 Plus, consider spending another $100<br />

to quadruple the storage. Those phones come with a paltry<br />

32 gigabytes, just half of what’s standard these days. If you<br />

don’t upgrade, you risk filling up your phone quickly with<br />

photos, video, songs and podcasts.<br />

Can a Holographic Screen Help a New<br />

Phone Break Out? By Anick Jesdanun<br />

NEW YORK (AP) — Most leading phones offer the same<br />

basics: Big screens, decent battery life and good cameras. So<br />

when a newcomer brings something innovative to the party,<br />

why is it difficult to break through a phone market dominated<br />

by Apple and Samsung?<br />

One such smartphone was released Nov. 2 from Red, a<br />

company with roots in digital cameras for movie productions.<br />

The new Hydrogen One has a holographic screen that<br />

produces 3D visuals without needing special glasses. It is<br />

launching with two major movies converted to this format<br />

and allows users to create and share their own videos shot<br />

with the phone.<br />

Red’s goals are modest — about 16 million units a year,<br />

based on Red’s stated target of 0.5 percent of Samsung’s<br />

sales. But Red will need customers beyond the tech elite<br />

and camera buffs; it’ll need their friends and friends of their<br />

friends. It doesn’t help that the Hydrogen One carries a hefty<br />

$1,295 price tag.<br />

“The Red Hydrogen One stands little chance of upsetting the<br />

smartphone status quo,” said Geoff Blaber, a research analyst<br />

at CCS Insight.<br />

Chipping away at Apple’s and Samsung’s dominance is much<br />

harder than it used to be because phone innovation isn’t so<br />

much about hardware any more, Creative Strategies analyst<br />

Carolina Milanesi said. What matters more, she said, is the<br />

software and artificial intelligence behind it.<br />

Consider Apple’s new iPhones. Sure, the new XR and XS models<br />

all have decent screens, battery life and cameras. But Apple<br />

has also been emphasizing such software-based features<br />

as augmented reality, artificial intelligence and automation<br />

using the Siri digital assistant. Or take Samsung’s Galaxy Note<br />

9. Signature features include the use of AI to automatically<br />

fine-tune images.<br />

While the Hydrogen One’s screen is different, Milanesi said,<br />

it’s not necessarily something the mass market will gravitate<br />

to.<br />

Red founder Jim Jannard said his phone is about making<br />

waves in a sea of smartphone sameness.<br />

“We don’t buy the same make, model or color of car that<br />

our next-door neighbor has,” he said. “It’s important to keep<br />

this industry pushing along ... and give people some new<br />

choice. What we’ve done is pretty nuts.”<br />

The phone started selling Nov. 2 through AT&T and Verizon<br />

in the U.S.<br />

Red calls the screen technology 4V, for four view, which is<br />

another way of saying it’s doubling what twin-lens 3D cameras<br />

produce by adding depth data to each image. There’s<br />

a special material under the screen that lets 4V photos and<br />

video appear to the viewer in 3D. Images that aren’t shot or<br />

converted to this format will look the same as they do on any<br />

other screen. Attempts to photograph a 4V screen will also<br />

produce images that don’t look any different.<br />

Yet the 3D wizardry indeed works, though it’s more pronounced<br />

in some scenes than others. Images of a soccer goalie<br />

blocking a shot feels realistic, but a waterfall at Yosemite<br />

National Park looks like video taken with a regular camera<br />

(though leaves in the foreground looked 3D). The Red phone<br />

might remind you of holographic stickers in which the view<br />

shifts slightly as you tilt them.<br />

The Warner Bros. studio is giving customers of parent company<br />

AT&T two free 4V movies: the first Harry Potter prequel,<br />

Fantastic Beasts and Where to Find Them, and Steven<br />

Spielberg’s Ready Player One, which is set in a virtual world.<br />

The studio plans to convert about a half-dozen other movies<br />

initially. Red will have tools for producers to convert existing<br />

3D video into the 4V format.<br />

The Hydrogen One also has twin lenses in the back to capture<br />

4V photos and video. Trouble is, people you share them<br />

with will get a normal image unless they also have a Hydrogen<br />

One.<br />

The phone also has a handful of 4V games.<br />

Red’s 4V could run into the same problems that virtual reality<br />

has faced. People haven’t been rushing out for headsets,<br />

while video creators haven’t been rushing out to make VR<br />

experiences. There’s a chicken-and-egg problem at play.<br />

Beyond the fancy screen, the phone is thick at a time Apple<br />

and Samsung make thinner phones. That’s done to fit in<br />

a bigger battery, with <strong>12</strong> percent more capacity than the<br />

super-charged Note 9. The sides have ridges to improve the<br />

grip. The phone has pins for expansion modules, such as<br />

an adapter for any standard SLR lens. (Incidentally, a major<br />

manufacturer that tried this modularization approach, LG,<br />

backed away from it after a year.)<br />

Jannard has a history of disrupting other industries, too. He<br />

previously founded Oakley, which became a force in sunglasses<br />

using many of the word-of-mouth techniques he is<br />

hoping to replicate with the new phone.<br />

“We’re not trying to win over the whole world,” he said.<br />

“We’re trying to provide a phone that we hope enough<br />

people like. Otherwise, I’m going to own the single most<br />

expensive cellphone in the world, and I’m happy with that.”<br />

RectorSeal Introduces Smart Water Leak<br />

Monitoring, Detection and Prevention System<br />

RectorSeal® LLC, Houston, a leading manufacturer of quality<br />

plumbing and HVAC/R products, introduces TripleGuard,<br />

a smart electronic water leak monitoring, detection and<br />

prevention system product line that guards against property<br />

damaging, infrastructure water source leaks in residential<br />

and commercial real estate.<br />

Available through North American plumbing and HVAC/R<br />

wholesalers, TripleGuard is ideal for any real estate owner<br />

or manager overseeing property with dish washers, clothes<br />

washers, sinks, hot water heaters, hydronic/plumbing piping<br />

and other potential water leak sources.<br />

TripleGuard consists of two products that are maintenance-free<br />

and installable in less than an hour: 1) the Triple-<br />

Guard Smart for Cloud-based monitored facility leak protection;<br />

and 2) the TripleGuard Active appliance lead shutoff,<br />

designed mainly for single-source protection such as water<br />

heaters.<br />

While the plumbing industry currently has many leak detectors,<br />

few brands actually proactively stop water flow and<br />

subsequent property damage while also enabling the user<br />

with cloud-based control remotely or onsite via smartphones<br />

or the Internet. “Statistics reveal North American water<br />

damage insurance claims total billions of dollars annually<br />

and 250-gallons (946-liters) of water can potentially leak<br />

daily from just an 1/8-inch (3-mm) crack in a pipe,” said Brian<br />

Ilagan, TripleGuard senior product manager.<br />

The TripleGuard Smart system includes:<br />

• Actuator shutoff unit for the supply water line. The actuator<br />

is a high-torque design that fits over a 3/4, 1, or 1-1/4-<br />

inch (228, 305, 381-mm) ball valve (sold separately) on a<br />

building or zone’s primary water supply piping. It operates<br />

wireless with 4 AA batteries. The actuator is designed<br />

to withstand fully-submersed natural flooding situations<br />

and in temperature extremes from -4°F to <strong>12</strong>4°F (-20°C<br />

to 51°C) temperatures The actuator automatically closes<br />

and opens the ball valve monthly to proactively prevent<br />

scale buildup, thus requiring no maintenance other than<br />

battery replacement every four years;<br />

• Two water leak detectors. The sensors require two<br />

AA-batteries and placement under a potential water leak<br />

source. Maintenance requires battery change out every<br />

two years;<br />

• A Cloud-connected HUB. A 915-Mhz wireless device<br />

connects to the Cloud via Wi-Fi or a hard-wired modem<br />

Ethernet connection. The smart device accepts wireless<br />

communications from the sensors, and then monitors sensor<br />

status (scalable up to 30 sensors/HUB). When a sensor<br />

detects water, the HUB receives the communication and<br />

then wirelessly signals the actuator to close. HUB maintains<br />

a historical record of sensors for troubleshooting<br />

and status reports.<br />

• A smartphone app. The app allows remote access to the<br />

HUB for monitoring and controlling operation. The app<br />

can also be used to manually shutdown the building or<br />

HUB zone water supply remotely when unoccupied.<br />

The TripleGuard Active is a one-piece actuator valve that<br />

monitors and detects water heater leaks. Its single 10-footlong<br />

(3-meter), umbilical cord-connected sensor placed in the<br />

water heater pan automatically deactivates the cold water<br />

shutoff valve when detecting a water leak presence. “Statistics<br />

reports that 75-percent of water heaters fail within <strong>12</strong><br />

years and cause property damage,” added Ilagan.<br />

The TripleGuard product line’s other features include:<br />

One-year product warranty;<br />

• Valve is NSF/ANSI Standard 61 (NSF-61) and NSF-372 certified<br />

for potable water;<br />

• Multiple kits can be observed simultaneously on a manifest<br />

monitoring system for Home Owner Associations<br />

(HOA), multi-family housing management departments,<br />

and other overseers of large facilities with multiple units:<br />

• Potential for reducing property insurance premiums and<br />

satisfying insurers’ water leak policy provisions;<br />

• Future generations will integrate with Internet of Things<br />

(IoT) platforms;<br />

Danfoss Variable-Speed Compressors<br />

With IDV Create Efficiency Opportunities<br />

Danfoss has added new 8.5-ton and 11-ton* variable-speed<br />

compressors with intermediate discharge valves to its popular<br />

VZH range, giving commercial cooling manufacturers the<br />

market’s most complete choice of variable-speed scrolls with<br />

qualified drives.<br />

The new inverter scrolls are ideal for data center close<br />

controls and rooftop units, enabling precise, energy-efficient<br />

cooling. These compressors are also an excellent fit for<br />

rooftop units, helping OEMs meet challenging new seasonal<br />

and part-load efficiency standards, like the US Department<br />

of Energy’s (DOE) energy conservation regulations beginning<br />

in 2023. Likewise, for chillers, the Danfoss VZH range will<br />

enable OEMs develop a competitive range of systems capable<br />

of exceeding the demanding Ecodesign Lot 21 targets coming<br />

into effect in 2021.<br />

According to Luigi Zamana, senior marketing director for<br />

Danfoss Commercial Compressors, “The extended VZH range<br />

gives OEMs the opportunity to work with a single, proven<br />

supplier of prequalified variable-speed compressor and drive<br />

Cooling manufacturers are therefore under pressure to improve<br />

part-load efficiency in order to satisfy DOE regulations<br />

and continue to sell units in major world markets. With their<br />

ability to continuously modulate capacity, variable-speed<br />

compressors are a key part of meeting this challenge.<br />

Danfoss VZH scrolls go even further. They feature intermediate<br />

discharge valves (IDVs), which prevent over-compression<br />

losses that compromise efficiency in standard scroll technology<br />

under part-load conditions. The result is a significant<br />

improvement in integrated efficiency scores. Efficiency is<br />

further improved with state-of-the-art permanent magnet<br />

motors that help reduce power consumption under all operating<br />

conditions.<br />

Tailor-Made for Rooftop Units and IT Close Controls<br />

Energy efficiency is particularly important in data center<br />

cooling applications. With round-the-clock cooling demand,<br />

each incremental reduction in power consumption has a<br />

large impact on energy bills, giving IDVs a clear advantage in<br />

making data centers more sustainable as IDVs deliver much<br />

higher system efficiency for the same cooling capacity, especially<br />

at very high evaporating temperatures (low pressure<br />

ratios) that are typical of data centers.<br />

But servers also need precise conditions to function reliably,<br />

and variable-speed technology gives the unparalleled ability<br />

to achieve a narrow, 0.54 °F (0.3 °C) temperature window,<br />

without sacrificing power usage effectiveness (PUE).<br />

Additionally, the VZH’s extended operating map and ability<br />

to work in a wide range of conditions, makes it an obvious<br />

choice for IT close control systems, as well as rooftop units in<br />

markets where seasonal efficiency is a priority.<br />

Prequalified Packages Accelerate Time to Market<br />

Danfoss is able to supply properly-sized compressors and<br />

drives as a matched, prequalified and certified package. This<br />

ability dramatically accelerates the development process,<br />

allowing OEMs to bring new, more efficient units to market<br />

faster.<br />

A Road Map to Lower GWP<br />

Currently, VZH compressors are approved for use with<br />

R-410A, a refrigerant with a Global Warming Potential<br />

(GWP) of less than 2500. Danfoss’ commitment to lower-GWP<br />

alternatives — including its new, 3000-m2 testing facility for<br />

flammable refrigerants — means we have spelled out a clear<br />

road map for a safe, managed transition before refrigerant<br />

phase-downs commence in earnest.<br />

Variable-Speed With IDVs: the Key to SEER, IPLV and IEER<br />

Worldwide, energy-efficiency standards are increasingly<br />

Larson Electronics Releases North/South<br />

ATEX/IECEX-Rated 35-Amp<br />

Explosion-Proof Contactor<br />

Electronics’ powerful explosion-proof contactor is made of<br />

copper-free aluminum with an electrostatically applied powder<br />

epoxy/polyester finish.<br />

The explosion-proof contactor is rated NEMA Type 3, 4,<br />

4X, 7 (B, D, D) and 9 (E, F, G) and is designed to withstand<br />

harsh environments and operating conditions. Ideal applications<br />

include hazardous locations, HVAC systems, industrial<br />

motors, compressors, chemical processing, welding, heating<br />

equipment, manufacturing sites and more. The EXP-CTR-3P-<br />

35A-240V-2X0.75NS is listed for the United States, Canada,<br />

Europe and Asia.<br />

“This contactor allows safe electrical connections in flammable<br />

Morehouse Offers Two New Portable<br />

Calibrating Machines<br />

Morehouse’s new portable models are for calibrating force-measuring<br />

devices with capacities from 25 lbf through 10,000 lbf<br />

YORK, Pa. (GLOBE NEWSWIRE) — Morehouse Instrument<br />

Company has introduced two portable calibrating machines.<br />

One of the machines is a 2,000 lbf capacity portable calibrating<br />

machine (PCM) which is capable of calibrating various<br />

types of load cells, hand-held force gauges, and other<br />

force-measuring devices with capacities from 25 lbf through<br />

2,000 lbf while providing stable control to within 0.01 lbf.<br />

The PCM solves a safety issue associated with small force<br />

measurement below 500 lbf. It eliminates the need for the<br />

technician to carry or stack weights, which protects employees<br />

as those weights are often heavy and can lead to various<br />

injuries.<br />

The other machine is a 10,000 lbf capacity portable benchtop<br />

calibrating machine (BCM). The benchtop machine allows for<br />

calibration of force-measuring equipment with capacities of<br />

100 lbf through 10,000 lbf. It takes up less than a 2’ x 2’ area<br />

and was designed to calibrate a large range of equipment.<br />

The system provides a fine control that enables the technician<br />

to calibrate several load cells, crane scales, dynamometers,<br />

and other force equipment while controlling the force<br />

to as little as 0.05 lbf throughout the range.<br />

Larson Electronics’ explosion-proof contactor is ideal for use in ATEX-rated,<br />

flammable and combustible sites.<br />

KEMP, Texas (GLOBE NEWSWIRE) — Larson Electronics, a<br />

Texas-based company with more than 40 years of experience<br />

spearheading the industrial lighting and equipment sector,<br />

announced the release of an explosion-proof contactor<br />

designed for secure connections to circuits and motors in<br />

ATEX-rated, flammable and combustible sites. This 35-amp,<br />

three-pole unit is compatible with 240V AC 50/60Hz and has<br />

a choice of a NO or NC configuration.<br />

The EXP-CTR-3P-35A-240V-2X0.75NS is a durable explosion-proof<br />

contactor featuring two 3/4” NPT hubs for the<br />

north and south sides of the unit – one for each side. Larson<br />

Ashrae Update<br />

ASHRAE Realigns Relationship With<br />

IAQA<br />

ATLANTA — ASHRAE has announced that an agreement has<br />

been reached with the Indoor Air Quality Association (IAQA)<br />

for IAQA to transition to an association management firm.<br />

IAQA became an affiliate of ASHRAE in 2015. In that relationship,<br />

IAQA’s operational base became integrated within<br />

ASHRAE’s headquarters operations in Atlanta, Ga. With this<br />

change, IAQA will take on a more independent management<br />

position. Both organizations are committed to continue collaborative<br />

programming that benefits all members involved.<br />

“ASHRAE has progressed strongly as a global society and<br />

our focus now turns to positioning each organization for<br />

long-term growth and leadership,” says <strong>2018</strong>-19 ASHRAE<br />

President Sheila J. Hayter. “The best way to accelerate that<br />

transformation is by separating our associations to uniquely<br />

position both ASHRAE and IAQA to lead their markets, while<br />

focusing strongly on the needs of our members.”<br />

During its affiliation, IAQA operated independently within<br />

ASHRAE’s organizational structure, maintaining its own<br />

brand and Board of Directors. Both associations viewed the<br />

initial partnership as an asset for the growth and development<br />

of each organization’s distinct membership base.<br />

“This change comes as a necessity to ensure the growth,<br />

expansion and financial stability of our membership and<br />

association,” says IAQA President Jay M. Stake. “IAQA will<br />

now be managed by AH, an association management company<br />

(AMC) with offices in Mount Laurel, N.J. and suburban<br />

Washington, D.C.<br />

IAQA will continue to offer corporate and individual memberships,<br />

education, conference and resources to indoor air<br />

quality professionals. ASHRAE will continue its longstanding<br />

leadership of IAQ sciences and technologies.<br />

A task force has been established to examine the best path<br />

forward for both organizations.<br />

ASHRAE Seeks Third<br />

Round of Comments on<br />

Legionella Guideline <strong>12</strong><br />

ATLANTA (Nov. 2, <strong>2018</strong>) – ASHRAE is seeking a third round of<br />

public comments on ASHRAE Guideline <strong>12</strong>- 2000R, Proposed<br />

Revision of Guideline <strong>12</strong>-2000, Managing the Risk of Legionellosis<br />

Associated with Building Water Systems. Guideline <strong>12</strong><br />

is open for a 45-day public review until Dec. 17. Those interested<br />

in reviewing and commenting on the guideline can do<br />

so through the ASHRAE Online Comment Database. In this<br />

Independent Substantive Change (ISC) public review draft,<br />

only revisions in strikethrough and underlined are open for<br />

comment.<br />

The purpose of ASHRAE Guideline <strong>12</strong> is to provide information<br />

and guidance to assist in control of legionellosis associated<br />

with building water systems. It also provides guidance<br />

useful in the implementation of ASHRAE Standard 188, “Legionellosis:<br />

Risk Management for Building Water Systems.”<br />

ASHRAE Guideline <strong>12</strong> is intended for use by owners of<br />

human-occupied buildings and those involved in the design,<br />

construction, installation, commissioning, management,<br />

operation, maintenance, and service of centralized building<br />

water systems and components.<br />

“This guideline addresses an important issue that impacts<br />

public health and safety, so feedback is critical,” said Paul<br />

Lindahl, committee chair for ASHRAE Standing Standard<br />

Project Committee (SSPC) 188, the committee responsible for<br />

writing Guideline <strong>12</strong>. “Guideline <strong>12</strong> will be a strong companion<br />

to ASHRAE Standard 188 in an effort to provide building<br />

owners with the resources needed to reduce the risk of<br />

Legionellosis and save lives.”<br />

The Centers for Disease Control and Prevention estimates<br />

there are between 8,000 and 18,000 cases of Legionnaires’<br />

disease in the United States each year, with more than 10<br />

percent of the cases fatal. Most are the result of exposure to<br />

Legionella associated with building water systems.<br />

Do your building engineers understand<br />

the importance of water treatment?<br />

1/3 of water used in commercial buildings is consumed by heating and cooling equipment. What<br />

you don’t know about the water in your building could be costing you. We will meet you at your<br />

facility, bring lunch for your team, and deliver training that gets your engineers’ attention.<br />

“HOH’s people take tremendous pride in the work they do<br />

and treat our water systems as if they were their own”<br />

1930s Hollywood Theater in Fort Worth<br />

Needs Pricey Face-Lift By Bud Kennedy | Fort Worth Star-Telegram<br />

Downtown Fort Worth’s hidden Hollywood Theater has been closed for around 40 years. Only an awning outside the Historic Electric Building Apartments<br />

hints that the mezzanine lobby, balcony and ornate auditorium of a 1,800-seat theater are hidden behind locked doors. (Steve Wilson/Star-Telegram via<br />

AP)<br />

FORT WORTH, Texas (AP) — Dark 41 years, a forgotten downtown<br />

movie theater flickered to life the other day, and for a<br />

few minutes Fort Worth relived the era of downtown glitz,<br />

showbiz premieres and Gone With the Wind.<br />

The Fort Worth Star-Telegram reports the 1930-vintage Hollywood<br />

Theater, sealed away for decades like some old movie<br />

monster’s secret crypt, opened to daylight for the first time<br />

in two generations as a crowd relived past grandeur and<br />

imagined a future restoration.<br />

Only an awning outside the Historic Electric Building Apartments<br />

hints that the mezzanine lobby, balcony and ornate<br />

auditorium of a 1,800-seat theater are hidden behind locked<br />

doors at 410 W. Seventh St.<br />

“I love old Fort Worth things,” said Casey Tibbetts, 36, president<br />

at the new Guaranty Bank & Trust location next door.<br />

He saw the theater and arranged public tours as part of the<br />

new bank’s open house.<br />

“When we picked this location, people started asking about<br />

the theater. We wanted people to come take a look.”<br />

Like an aging movie star, the Hollywood needs an expensive<br />

face-lift.<br />

Restoring a typical theater costs from $5 million to $10 million,<br />

according to the National Trust for Historic Preservation.<br />

The lower auditorium floor and seats are gone, stripped and<br />

removed to make room for residents of the adjacent apartments<br />

to park underneath.<br />

But the balcony, walls, ceiling and screen area remain, along<br />

with the mezzanine, marble staircase and part of the lobby,<br />

in a style described in one opening-day 1930 news report as<br />

Georgian modernist.<br />

Houston-based owner Tradewind Properties has been<br />

advertising the 3,000-square-foot lobby and concourse and<br />

<strong>12</strong>,000-square-foot theater for lease.<br />

“I personally think it sets up nicely for a performance venue,”<br />

said Andy Taft, president of Downtown Fort Worth, Inc.<br />

“I was surprised at how intact the features are inside. It<br />

doesn’t take much imagination to see the potential.”<br />

It’d need disability access and an auditorium floor. But it<br />

could easily become a black-box performance theater or<br />

music club.<br />

The Hollywood is inside the Electric Building, built in 1929 by<br />

Houston investor Jesse H. Jones for Texas Electric Service Co.,<br />

now TXU Energy.<br />

The Historic Star-Telegram Building, converted in 2013 to<br />

MorningStar Partners, is next door. (The Star-Telegram is now<br />

in a different Jesse Jones tower at 808 Throckmorton St.,<br />

built in 1930 as the Fair Building.)<br />

The Hollywood was built in 1930, just when the industry<br />

was switching from silent movies and musicians to “talking<br />

pictures,” so it only has a screen, not a stage. The first movie<br />

shown was director Frank Capra’s “Flight.”<br />

In 1940, the Hollywood was in the spotlight twice.<br />

In February, it unreeled Fort Worth’s first-run showings of<br />

“Gone With the Wind,” to audiences that included Civil War<br />

veterans and that stood in lines circling the block.<br />

That September, the Hollywood and the larger Worth Theater<br />

one block east co-hosted the city’s first world movie<br />

premiere: “The Westerner” with Gary Cooper, telling the<br />

story of legendary Texas frontier Judge Roy Bean.<br />

The movie was partly shot at Star-Telegram owner Amon G.<br />

Carter’s Shady Oak Ranch. A Houston movie critic described<br />

the premiere, hosted by comedian Bob Hope, as classic Fort<br />

Worth:<br />

“Cowboys in full regalia slouched around in boots, cowboy<br />

Stetsons at rakish angles.<br />

The dinner out at Amon G. Carter’s ranch looked like a<br />

miniature Academy Awards banquet. In cowboy outfit and<br />

riding his Palomino pony, he greeted the celebrities. ‘I can<br />

think of nothing more appropriate than having the premiere<br />

here where the West begins,’ he said.”<br />

It was the night Hollywood came to the Hollywood.<br />
